摘要： Various methods and apparatuses are described in which an array of optical gain mediums capable of lasing are contained in a single integral unit. The array may contain four or more optical gain mediums capable of lasing. Each optical gain medium capable of lasing supplies a separate optical signal containing a band of wavelengths different than the other optical gain mediums capable of lasing in the array to a first multiplexer/demultiplexer. A connection for an output fiber exists to route an optical signal to and from a passive optical network.

摘要： An optical heterodyne detection system includes a tunable optical pre-selector that is adjusted to track the frequency of a swept local oscillator signal. The tunable optical pre-selector is adjusted in response to a measure of the frequency of the swept local oscillator signal and in response to a measure of a portion of the swept local oscillator signal after the portion of the swept local oscillator signal has optically interacted with the optical pre-selector. In an embodiment, at least some portion of the swept local oscillator signal is modulated before it interacts with the optical pre-selector. In an embodiment, the portion of the swept local oscillator signal that interacts with the pre-selector is detected and used in a feedback control circuit to generate a control signal which causes the error between the center frequency of the pre-selector and the frequency of the swept local oscillator signal to be small.

The light source includes an output laser having a first optical cavity that includes a bottom mirror located outside of the optical fiber, and a top mirror that includes a reflector located within the optical fiber. An active region between the top and bottom mirrors generates light of the first wavelength, preferably through optical pumping at a second wavelength. The reflector is preferably a Bragg reflector and may include a mechanism for altering the wavelength of the light reflected thereby as well as the distance between the top and bottom mirrors. The pumping light is preferably generated by a pumping laser that includes a second electrically pumped optical cavity having a top mirror that is electrically connected to the bottom mirror of the first optical cavity.

摘要： An optical amplifier comprises a wavelength tunable filter, one or more optical gain stages, and a controller for controlling a spectral profile of the wavelength tunable filter in response to a measured spectral characteristic of the amplifier. The controller may also control gain of the gain stage(s). The controller determines the filter spectral profile necessary to obtain a desired amplifier spectral characteristic. The spectral characteristic may, for example, be a power spectral output of the amplifier or a gain profile of the amplifier. The amplifier may incorporate a dispersion compensator. The controller may control a spectral profile of the wavelength tunable filter and gain of the dispersion compensator. A tunable fiber light source is also described.

摘要： A tunable optical resonator constructed from a fixed mirror and a moveable mirror. The fixed mirror is attached to a substrate having a first electrically conducting surface. A support member having the moveable mirror supported thereon and a second electrically conducting surface is suspended above the substrate such that the moveable mirror is separated from the fixed mirror. A light output port transmits a light signal of a wavelength determined by the distance between the fixed and moveable mirrors. An optical circuit measures the power level of the light signal and generates an electrical signal that depends on the measured power level. A frequency adjustment circuit, responsive to the electrical signal and a tuning voltage, applies an electrical potential between the first and second electrically conducting surfaces. The electrical potential causes the distance to remain at a distance determined by the tuning voltage independent of the power level for power levels less than a predetermined power level. The resonator can be used to construct a laser by incorporating an active layer for amplifying light trapped in the cavity. The resonator can also be used a tunable optical filter by including an input port for receiving a light signal that is to be filtered. In one embodiment of the invention, a feedback circuit consisting of an optical coupler, photodiode, amplifier, and signal adder is used to generate the potential between the first and second electrically conducting surfaces.

摘要： Bistable switchable waveguide includes a guide layer constructed from a layer having a first index of refraction when the molecules of the material are aligned in a first direction and a second index of refraction when the molecules are aligned in a direction orthogonal to the first direction. The guide layer is sandwiched between first and second surfaces that are in contact. The first surface causes the molecules of the guide layer adjacent to it to be aligned in the first direction. The second surface also includes a third region in which the second surface causes the molecules of the guide layer adjacent to it to be aligned in a second direction. The waveguide has first and second electrodes for causing the molecules of the guide layer to be aligned in a second direction that is the second direction in a region bounded by the third region and first surface.

摘要： A light guiding element for routing a light signal between an input port and an output port or for blocking the propagation of the light signal between the input and output ports depending on the state of the switching element. The guiding element utilizes a beam splitter for separating the input light signal into physically separated first and second polarized light signals, the first light signal having a polarization that is orthogonal to that of the second light signal. A first polarization rotator rotates the polarization of the first light signal such that the polarization of the first light signal is parallel to that of the second light signal. A first waveguide having first and second states operates on the first light signal such that the first waveguide guides the first light signal along a predetermined path in the first state while not guiding the first light signal in the second state. A second waveguide having first and second states operates on the second light signal such that the second waveguide guides the second light signal along a predetermined path in the first state while not guiding the second light in the second state. A second polarization rotator rotates the polarization of the second light signal such that the polarization of the second light signal is orthogonal to that of the first light signal. A beam combiner then combines the first and second light signals and couples the same to the output light port.

摘要： An improved optical switch allows for the testing, calibration and monitoring of optical switch points in an optical switching matrix. A test column and a test row of additional switch elements and optical paths enable the improved optical switch to provide testing, calibration and monitoring of each optical switch point in the optical switch matrix using a test input source and a test output receiver. The improved optical switch may also be used to test for the presence of light at any input and to inject a test signal into the matrix in order to test for the presence and quality of light at any output.

摘要： An optical circulator having first, second, and third ports. The optical circulator includes a beam splitter and a plurality of Faraday stages. The beam splitter is connected to the first and third ports and separates a first light signal entering the first port into first and second outgoing light signals. The beam splitter also separates a second light signal entering the third port into third and fourth outgoing light signals. The first, second, third, and fourth outgoing light signals are spaced-apart from one another. The first and second outgoing light signals include, respectively, orthogonal polarization components from the first light signal, and the third and fourth outgoing light signals include, respectively, orthogonal polarization components from the second light signal. The Faraday stages, including a first Faraday stage and a last Faraday stage, being arranged in series. The first Faraday stage receives light from the beam splitter, and the last Faraday stage is positioned so as to provide light to the second port. The second port and the walk-off directions and directions of rotation of the Faraday stages are chosen such that light entering the first port exits the second port, light entering the second port exits the third port, and light entering the third port is prevented from exiting the first and second ports.
