摘要： Optical waveguides (11, 12) are formed on a substrate (10), a thin film (13) whose refractive index is optically lower than the refractive indices of the optical waveguides (11, 12) is formed on the surface of the substrate, and a surface-acoustic-wave waveguide (16) is formed on this thin film (13) so as to cross the optical waveguides (11, 12) in a direction oblique thereto. The optical waveguides (11, 12) are not directly influenced by the position of the SAW waveguide (16) and the phase matching condition regarding the optical waveguides is not changed, whereby the sidelobe characteristic of an optical filter is not degraded because of assigning of weights to the SAW intensity.

摘要： A light beam on a single optic fiber carries time division multiplexed information originating from multiple sensors driven from a single light source. An optical switch apparatus coupled in series between the source and the sensors switches the light beam of the source between ON and OFF states. The switch apparatus includes an electro-optic switch and an acousto- optic switch coupled in series with the electro-optic switch. A controller and drivers for the electro-optic and acousto-optic switches produce in an appropriate time sequence control signals resulting in a desired ON and OFF time of the light beam being switched.

摘要： A system for exciting flexural waves on an optical fiber (102) is provided. The system includes a substrate (114, 118), an actuator (106), and a mechanical optical fiber coupling (104). The actuator is formed of an electromechanical transducer material. The actuator is mounted on the substrate. The mechanical optical fiber coupling (for example, an adhesive media) forms a secure mechanical connection between the actuator and the optical fiber. The mechanical optical fiber coupling is configured for communicating mechanical vibrations from the actuator to the optical fiber. However, it should be understood that the mechanical optical fiber coupling is exclusive of a tapered horn.

摘要： The device comprises an optical waveguide and an acoustic wave generating device. The waveguide has an optical band gap and a sharp electronic transition (e.g. an excitonic transition) in the band gap, and the acoustic wave generating device generates acoustic waves within the waveguide. Light passing through the waveguide is of a frequency within the band gap of the waveguide and is nearly resonant with the sharp electronic transition. The wave generating device is arranged to generate acoustic waves so as to induce optical band gas in the polariton spectrum, thereby affecting the transmission of the light passing through the waveguide, the transmission of which is thereby affected.

摘要： A two-port guided wave tunable filter in a birefringent electrooptic and/or acoustooptic substrate material includes two 3-port, symmetric Y-branch beamsplitters connected by two waveguide sections in which phase-matched polarization coupling occurs, with an input port and an output port. The optical path difference between the beamsplitters is half an optical wavelength, and the polarization coupling regions between the beamsplitters are relatively displaced by an odd integral multiple of half the spatial period of the pertubation responsible for the coupling. In an electrooptic tunable filter embodiment, the polarization coupling in the waveguides is caused by a spatially periodic strain-inducing film and tuning results from an applied electric field. In an acoustooptic tunable filter embodiment, polarization coupling results from a surface acoustic wave and tuning is accomplished by changing the acoustic frequency. Alternatively, four port electrooptic and acoustooptic tunable filters are formed by replacing the 3-port beamsplitters with 4-port directional couplers.
