摘要： PROBLEM TO BE SOLVED: To provide a laser light source system in which ASE(amplified spontaneous emission) noise is reduced by connecting first port of an optical circulator to a light source, its second port is connected to an optical fiber section, and its third port, which is unconnected to the light source, is connected to the output port of the system. SOLUTION: A first port of an optical circulator 12 is connected to a laser light source 10 by an optical fiber 11, and a second port of the circulator is connected to an optical fiber section 13 which has a fiber Bragg grating 14 and which has a nonreflecting end terminal 15. A third port of the optical circulator 12 is connected to an optical fiber 16 which carries the laser output, which has passed through the circulator 12 and been acted upon by the fiber Bragg grating 14. With this constitution, only the signal light of a predetermined wavelength is carried to the optical fiber 16 for the light output with a low noise level, reducing the ASE noise of the system.

摘要： PROBLEM TO BE SOLVED: To adjust a resistor so as to exclude higher harmonic, by arranging a first and a second semiconductor diodes which are connected in antiparallel constitution with each other and are connected in parallel with a signal source. SOLUTION: A compensation semiconductor diode 14 and light source semiconductor diode 12 are connected with an AC signal source 20, in the relation of antiparallel. The light source semiconductor diode 12 and the compensation semiconductor diode 14 contain a bias network having an independent DC bias source isolated from the AC signal source 20. A first bias source 16 provides a DC bias to the light source semiconductor diode 12, and a second bias source 18 provides a DC bias to the compensation semiconductor diode 14. The second bias source 18 provides a reverse bias to the compensation semiconductor diode 14. The above reverse bias can be adjusted by changing the resistance of a variable resistor 34, and higher harmonic distortion can be reduced.

摘要： An add/drop device is described that allows channels from a multi-channel optical path to be dropped to a device and a new or modified channel to be added to the multi-channel optical path. The device thereby has access to a channel from the multi-channel optical path without having access to all of the channels. In one embodiment, the add/drop device of the invention includes one or more intermediate ports (330, 340) and a switch (360). The intermediate ports (330, 340) communicate the channels not dropped by the add/drop device and the switch (360) selectively optically couples the dropped channel either to the device or to be added back into the multi-channel path. The switch also selectively optically couples the new or modified channel to be added to the multi-channel path. The one or more intermediate ports (330, 340) allow multiple add/drop devices to be optically coupled together to provide a configurable add/drop mechanism.

摘要： Optical filters, filter systems, and methods for filtering optical signals transmitted along optical fibers (12, 14) provide enhanced filter performing by combining the capabilities of different types of filters particularly for dense wavelength division multiplexed systems. More specifically, the spectral skirt or transition wavelength range between a pass band wavelength range and a blocked wavelength range of a thin film pass band or dichroic filter (16) is enhanced by arranging the thin film filter (16) in series with one or more Fiber Bragg Gratings (18, 20). The Fiber Bragg Gratings (18, 20) will generally reflect a portion of the signal within the spectral skirt or transition wavelength range of the thin film filter (16). Although short Fiber Bragg Gratings generally block a quite narrow range of signals, the steep spectral skirt of the grating, when combined with the broader wavelength response of a thin film bandpass or dichroic filter (16), results in a composite filter structure which exhibits the beneficial characteristics of each of its components.

摘要： The present invention provides fiber optic couplers (20) for use with at least three optic fibers (10). The optic fibers (10) arranged in linear-array, that is, the optical fibers (10) are coupled side by side. The fibers (10) along either end of the linear-array are coupled only to a single fiber (10A), while the remaining fibers are generally coupled between only two adjacent fibers (10). Generally, at least one of the fibers (10) has a propagation constant different than the other fibers (10). Such variations in the propagation constant are used to vary the coupling coefficients among the fibers (10) of the linear-array, thereby providing a repeatable mechanism, to vary coupled power ratios among the fibers (10) of coupler (20). Theoretical calculations and empirical experience have shown that varying the propagation constant of fibers (10) among a linear-array, generally by pre-pulling the fibers (10) by varying amounts, allows repeatable manufacturing of 1x3, 3x3, 1x4, 4x4, 1xN and even NxN fiber couplers having even coupled power ratios.

摘要： A fiberoptic coupler capable of many functions is presented. The basic fiberoptic coupler has a first sleeve (33), a second sleeve (36), a first collimating GRIN (34) or conventional lens, and a second collimating lens (35) or conventional lens. The first sleeve (33) holds end sections of two or more input optical fibers (30, 31) along the longitudinal axis of the sleeve. The second sleeve (36) holds an end section of at least one output optical fiber (32). The end face of the second sleeve faces the first sleeve end face. The first collimating GRIN (34) or conventional lens in front of the first sleeve end face collimates light signals from the input optical fibers and the second collimating GRIN (35) or conventional lens in form of the second sleeve end face focusses light signals from at least one of the input optical fibers (30, 31) into the single output fiber (32), or at least one of the output optical fibers (32, 39). With only one output fiber the coupler operates as a combiner. If more than one output fiber is held by the second sleeve, the input and output fibers can be arranged so that a light signal from one input fiber is sent to one output fiber. For added functionality, optical elements, such as isolators and wavelength-dependent filters can be inserted between the first and second collimating lenses.

摘要： The present invention provides for a compensating element in the form of a birefringent plate (20) in an optical isolator which uses a first GRIN lens to collimate the light signal from an input optical fiber, a first birefringent polarizer wedge (12), an optical Faraday rotator (13), a second birefringent polarizer wedge (14), and a second GRIN lens to recollimate the light signal to an output optical fiber. Polarization mode dispersion through said optical isolator is substantially reduced by arranging the fast optical axis of the plate (20) to be perpendicular to the fast optical axis of the polarizer (12) on the same side of the Faraday rotator (13) as the plate (20) and selecting the thickness (d) of the plate (20) in a predetermined manner. The present invention also allows for minimization of "walk-off", which also contributes to some polarization mode dispersion through the isolator.
