摘要： A laser apparatus for nonlinear conversion of light is disclosed utilizing a laser diode having a reflective back facet and a front facet having a reflectance of less than about 1% for emitting a multifrequency optical beam, and a nonlinear optical element for receiving the multifrequency optical beam and for generating a frequency-converted radiation. An external frequency-selective reflector is provided for power and spectral stabilization of the multifrequency optical beam, and for confining its optical spectrum within a bandwidth of efficient nonlinear conversion in the nonlinear optical element. The laser diode reflective back facet and the external frequency-selective reflector form an extended laser cavity. In operation, the multifrequency optical beam contains a plurality of longitudinal modes of the extended laser cavity which are confined within the frequency conversion bandwidth of the nonlinear element. The external frequency-selective reflector may comprise a waveguiding element such as a single-mode fiber incorporating a Bragg grating, and may also comprise a Fabry-Perot etalon.

摘要： A 1½×2 optical switch has two GRIN lenses, each lens having two ports on its respective outward end face. The switch has a transmissive wedge-shaped switching element disposed between the GRIN lenses. When the switching element is disposed in the path between the GRIN lenses, a single connection is established between a port of the first GRIN lens and a port of the second GRIN lens, while light is prevented from coupling between the remaining ports.

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.

摘要： A non-coherent light emitting device having at least one organic light emitting or organic charge transporting layer and a structure providing a Bragg grating associated with the light emitting layer is described. The organic light emitting layer having liquid crystalline material is treated to provide alternating zones of isotropic and liquid crystalline material. The combination of alternating zones with the dichroic effects of the aligned zone produces a pseudo 2-D Bragg grating within the light emitting layer.

摘要： A tunable narrow linewidth laser is provided, wherein an adjustable etalon structure is employed to simultaneously tune the wavelength of the laser transmission and the length of the laser cavity. The etalon structure is an effective, relatively thick shear plate comprised of transparent matched wedge-shaped substrates and a pair of parallel, partially transmissive mirrors with a space therebetween. Rotation of the etalon structure relative to the laser input changes the angle of incidence to the first substrate and the etalon angle, thereby changing the wavelength of the laser light and also changing the length of the external laser cavity. Thus, reliable frequency tuning is achieved, without mode hopping.

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 linearized 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 realized. 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 realized.

摘要： A display light source (230) includes a gain media (232), an output reflector (246), and a wavelength converter (244) that cooperate to generate a source output beam (260). The gain media (232) generates a media output beam (247) that exits an output facet (232B) of the gain media (232). The media output beam (247) has a first spectral frequency range and a relatively large number of modes. The output reflector (246) is spaced apart from the gain media (232), and the output reflector (246) forms a portion of a laser cavity (251). The wavelength converter (244) is positioned within the laser cavity (251). The wavelength converter (244) converts at least a portion of the media output beam (247) from the first spectral frequency range to a converted beam (258) having at a secondary spectral frequency range. For example, the wavelength converter (244) can double the frequency of the media output beam (247). Additionally, the light source (230) can include a wavelength controller (238) that controls the number of modes that are lasing in the laser cavity (251), and that controls the spectral width and the center wavelength of the light that is lasing in the laser cavity (251)

摘要： An apparatus is described for controlling the optical path length in an optical device, e.g. an interferometer, and more importantly to maintaining the optical path length difference in an interferometer. The apparatus may include an adjustable plate optically coupled with a beamsplitter. The plate may be rotated such that its surface receives light propagated from the beamsplitter at a non-zero incident angle. In one embodiment, temperature sensitivity is addressed by ensuring that the refractive index of the plate is greater than the refractive index of the beamsplitter. In another embodiment, the apparatus includes combination spacers having a component selected in dependence upon a composition, thickness, and orientation of the adjustable plate.
