Abstract: Described herein is an optical phase modulator (20) including a liquid crystal element (22), disposed between a pair of opposing electrodes (24) and (26). The electrodes (24, 26) are electrically driven for supplying an electric potential V across the liquid crystal element (22) to drive the liquid crystals within element (22) in a predetermined configuration. Electrode (26) includes a grid of individually drivable pixel regions (28), at least some of which include a sub-wavelength grating structure that provides an anisotropic refractive index profile in orthogonal lateral dimensions, thereby creating an effective material form birefringence. Light incident through liquid crystal element (22) and onto electrode (26) is reflected and experiences a relative phase difference of 180° between its constituent orthogonal polarization components, thereby rotating each polarization component into the orthogonal orientation upon reflection.

Abstract: Described herein is a laser (1) having a cavity for supporting oscillation of an electromagnetic signal to provide lasing action. A gain element (5) provides a source of stimulated emission for amplifying the oscillating signal. The laser also includes a wavelength selective element (7), which includes a reflecting element and a polarization modifying element. The reflecting element selectively defines a predetermined wavelength and the polarization modifying element selectively modifies the polarization of the signal component at the predetermined wavelength so as to provide high selectivity. The wavelength selective element (7) rotates the signal polarization at the predetermined wavelength into an orthogonal state. A polarization filter (9) filters out the signal components having wavelengths not corresponding to the predetermined wavelength and a polarization rotation element (11) again rotates the polarization of the signal into an orthogonal state.
