Abstract: A method of fabricating a switchable liquid crystal polarization grating includes creating a degenerate planar anchoring condition on a surface of a reflective substrate. An alignment layer may be formed on a transmissive substrate and may be patterned to create a periodic alignment condition therein. The transmissive substrate including the patterned alignment layer thereon may be assembled adjacent to the surface of the reflective substrate including the degenerate planar anchoring condition thereon to define a gap therebetween. A liquid crystal layer is formed on the surface of the reflective substrate including the degenerate planar alignment condition. The liquid crystal layer may be formed in the gap directly on the alignment layer such that molecules of the liquid crystal layer are aligned based on the periodic alignment condition in the alignment layer. Related fabrication methods and polarization gratings are also discussed.

Abstract: A method and apparatus for designing a device to operate in a coupling mode, a detection mode, or a reflection mode for incident light. The incident light has a wavelength λ and is incident upon a semiconductor structure of the device at an angle of incidence (θi). A voltage (V) is applied to the device. Each mode may be designed for an ON state and/or OFF state. For the coupling mode and detection mode, the ON state and OFF state is characterized by high and low absorption of the incident light, respectively, by the semiconductor structure in conjunction with the applied voltage V and angle of incidence θi. For the reflection mode, the OFF state and ON states is characterized by a shift in the optical path length of λ/2 and about zero, respectively, in conjunction with the applied voltage V and angle of incidence θi.

Abstract: The configurations of an electro-optic Bragg deflector and the methods of using it as a laser Q-switch in a Q-switched laser and in a Q-switched wavelength-conversion laser are provided. As a first embodiment, the electro-optic Bragg deflector comprises an electrode-coated electro-optic material with one of a 1D and a 2D spatially modulated electro-optic coefficient. When a voltage is supplied to the electrodes, the electro-optic material behaves like a Bragg grating due to the electro-optically induced spatial modulation of the refractive index. The second embodiment relates to an actively Q-switched laser, wherein the electro-optic Bragg deflector functions as a laser Q-switch. The third embodiment of the present invention combines the Q-switched laser and a laser-wavelength converter to form a Q-switched wavelength-conversion laser, wherein the EO Bragg deflector can be monolithically integrated with a quasi-phase-matching wavelength converter in a fabrication process.
