摘要： The present invention relates to an isolated polarization beam splitter or combiner, for joining light from different inputs into one common port, and for dividing a beam of light into orthogonal polarizations. In both modes of operation, the splitter/combiner provides isolation preventing transmission of light in a reverse direction. As a splitter, a beam of light is separated through a birefringent material into sub-beams of orthogonal polarization components, and each sub-beam is passed through a non-reciprocal polarization rotator to rotate the polarization so that a reflected beam, or other counter-transmitted light cannot return on the same path through the birefringent material to the source. As a combiner, two separate beams of light are launched with known orthogonal polarizations into a first birefringent material, passed through a non-reciprocal polarization rotator and then combined as orthogonal polarizations into a single output port. Advantageously, by providing the splitting or combining function in a same isolating device, insertion losses are reduced and the device is smaller and more cost effective. As a further advantage, a polarization beam splitter/combiner is provided in which the optical path length for the two separated orthogonal polarizations traveling through a birefringent crystal is equal, while still permitting the economical use of birefringent crystals with an uncollimated beam of light.

摘要： An optical switch is disclosed having 4-ports. The switch consists of a first GRIN lens having 2 ports (1 and 3) adjacent its outwardly facing end face, on opposite sides of an optical axis of the lens. A second GRIN lens is disposed to receive light from the first GRIN lens and has two ports (2 and 4) adjacent its outer end face, on opposite sides of an optical axis. In a first state, a first port (1) from the first GRIN lens couples light with port (2) of the second GRIN lens, and a second port (3) of the first GRIN lens simultaneously couples light with another port (4) of the second GRIN lens. A movable optical element, that when disposed in the path between first and second GRIN lens, provides only a single connection between a port of the first GRIN lens (1) and a port of the second GRIN lens (4) while preventing light from coupling between the other two ports (2 and 3). Hence a 1 ½ x 2 optical switch is disclosed. Furthermore, the optical switch is disclosed having multiple input and output ports. The switch consists of a first GRIN lens having 2 ports adjacent its outwardly facing end face. A second GRIN lens is disposed to receive light from the first GRIN lens and has two ports adjacent its outer end face. In a first state, a first port from the first GRIN lens couples light with a first output port of the second GRIN lens. In a second state, a movable optical element in the form of a light transmissive wedge having a reflective surface, is disposed in the path between first and second GRIN lens, providing a connection between a port of the first GRIN lens and a second port of the second GRIN lens. In a third connect state, the reflective surface of the wedge connects a port of the first GRIN lens and an output port in the same first GRIN lens. Hence an N x M optical switch is disclosed.

摘要： The present invention relates to an arrayed waveguide grating (102) having a reflective input that permits variable coupling to adjust the center wavelength. The present invention has found that by providing an arrayed waveguide grating (102) having one or more precisely positioned input waveguides (10,40) coupled through a reflective lens assembly (30,32), for providing a lateral offset to a signal propogating from the input waveguide (10,40) to the planar waveguide (12), and for focusing a reflected input signal at a selected input point of the input planar waveguide (12), alignment and tuning of an input and assembly can be improved and simplified. Advantageously, variable coupling parameters can be incorporated into the reflective coupling including input position, waveguide taper (42) and planar waveguide length increment (44) to provide relatively simple tuning in an integrated device. Compensation for polarization effects and thermal effects can also be provided in the reflective coupling.

摘要： A circuit for de-interleaving or interleaving multichannel optical signals having a predetermined inter-channel frequency spacing, uses a plurality of sequentially coupled periodic filters of a similar free spectral range, for example Fabry-Perot etalon-based interleavers/de-interleavers. The spectral response of the consecutive filters is shifted to accommodate different channel groupings. The free-spectral range of each of the interleavers is similar and the channel period is larger than two adjacent inter-channel frequency spacings of an input optical signal.

摘要： A micro-optical delay element for a polarization time-division multiplexing scheme is disclosed wherein two light beams are provided to a polarization beam splitter/combiner (PBS/C) in the absence of optical fibre. At least one beam exiting a modulator is collimated and reaches the (PBS/C) unguided as a substantially collimated beam. In this manner the polarization state of the beam is substantially unchanged. This obviates a requirement for polarization controllers.
