摘要： A double stage isolator is formed of face-to-face slabs or sheets of materials that will suitably split, combine, non-reciprocally rotate to ensure isolation in a reverse direction from output ports to respective input ports of any light launched into the input ports. A right angled Porro-prism is disposed at an end of the affixed together slabs having planar faces to direct light launched in a folded fashion to the output ports. A half waveplate is used in addition to beam splitter combiners and non-reciprocal rotators means that rotate the light by 90 degrees so as to pass a single beam in a forward propagating direction and to interchange the polarization of two sub-beams that pass through from an output port to an input port in a reverse direction.

摘要： An M×N wavelength-selective switch (WSS) is provided. M input ports launch M input beams towards a wavelength-dispersing system, which disperses the M input beams into M×K sub-beams at K wavelength bands. A redirecting system redirects the M×K sub-beams towards a first 1×K switching array, which selects K sub-beams from the M×K sub-beams. The redirecting system blocks the (M−1)×K non-selected sub-beams, but re-images the K selected sub-beams onto a second 1×K switching array by means of at least one relaying element having optical power. The second 1×K switching array routes the K selected sub-beams to N output ports. The redirecting system redirects the K selected sub-beams towards the wavelength-dispersing system, which combines any selected sub-beams that are routed to a same output port. The N output ports then output the K selected sub-beams.

摘要： A system for wavelength locking i.e. for maintaining a frequency of an optical signal to within predetermined limits has means for splitting part of the controlled optical signal into at least three sub-beams of which one is a reference beam and two others are provided to an optical element having a periodic output response and to a filter having a monotonic output response. The three detected outputs are analyzed and processed to determine accurately the wavelength of the optical signal and to produce a correcting signal if it is not within the predetermined limits.

摘要： A laser system is disclosed wherein a tunable laser signal has encoded within it information related to its wavelength at any instant in time. This encoding in one example is performed by modulating the signal to contain its wavelength information. This is particularly useful in a distributed system for testing optical components, wherein at a test site, the test station must determine the wavelength of light at which a component was tested.

摘要： An optical device for rerouting and modifying an optical signal that is capable of operating as a dynamic gain equalizer (DGE) and/or a configurable optical add/drop multiplexer (COADM) is disclosed. The optical design includes a front-end unit for providing a collimated beam of light, an element having optical power for providing collimating/focusing effects, a diffraction element for providing spatial dispersion, and modifying means which in a preferred embodiment includes one of a MEMS array and a liquid crystal array for reflecting and modifying at least a portion of a beam of light. The modifying means functions as an attenuator when the optical device operates as a DGE and as a switching array when the optical device operates as a COADM. Advantageously, this invention provides a 4-f system wherein a preferred embodiment the element having optical power is a concave reflector for providing a single means for receiving light from the front-end unit, reflecting the received light to the dispersive element, receiving light from the dispersive element, and providing dispersed light to the modifying means. Conveniently and advantageously, this same concave reflector is utilized on a return path, obviating the requirement of matching elements. In one embodiment a single focussing/collimating lens is provided substantially at a focal plane of the element having optical power.

摘要： A method and circuit is disclosed wherein two beams exiting opposite ends of a resonant optical cavity, such as a Fabry-Perot (FP) etalon for example, are provided via waveguides or via free space directed by mirrors to a combining region where the beams can interfere with one another to provide a desired output response. In one embodiment, multiplexed channels of light can be demultiplexed by the device described heretofore, or alternatively, the phase relationship between these two beams can be altered prior to their being combined to provide, for example, a linearized output response useful in applications such as wavelength locking. By varying the reflectivity of the optical cavity reflectors and/or by varying the phase relationship between the two beams exiting the optical cavity, a variety of desired output responses can be realized.
