    摘要: The present invention relates to an interferometer useful in the interleaving and deinterleaving of optical wavelength channels. Typically the invention comprises a beamsplitter and two resonators, e.g. GT etalons or ring resonators. The beamsplitter splits an input beam of light into a first sub-beam directed to follow a first path and a second sub-beam directed to follow a second path. The first resonator has a first effective cavity length and receives the first sub-beam. The second resonator has a second effective cavity length and receives the second sub-beam. The first path and the second path have an effective optical path difference approximately equal to one-half the first effective cavity length. In one embodiment, the front plates of the GT etalons each have a different reflectivity, and are selected to provide a desired spectral response. In another embodiment, the two resonators are slightly de-phased from one another such that the positive dispersion slope of the first resonator is aligned with the negative dispersion slope of the second resonator. Polarization-based versions of the invention are disclosed, in which a single resonator receives both sub-beams, which are orthogonally polarized. Single etalon versions of the invention are also possible, in which a beam is separated into sub-beams (i.e. reflected and transmitted beams) within a non-linear interferometer, and then re-combined outside the interferometer with the appropriate effective optical path length delay therebetween.

    摘要: A method and circuit is disclosed wherein two waveguides coupled to an optical resonant ring resonator are further coupled such that beams propagating therein 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 linearised output response useful in applications such as wavelength locking. By varying the reflectivity of the FSR and the coupling ratios and/or by varying the phase relationship between the two beams, a variety of desired output responses can be realised. By providing suitable coupling ratios and providing optical path lengths of the two waveguides which are identical between the ring resonator and the couplers coupling the two waveguides as well as having the couplers placed 180 degrees opposite to each other, an interleaver/de-interleaver function is realised. In other embodiments, different forms of optical cavity resonators (etalons) are used instead of the ring resonator.

    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.
