摘要： A tunable wavelength-selective filter includes a glass substrate, a transparent electrode layer, a highly reflective mirror, an alignment layer, a liquid crystal layer, another alignment layer, a transparent material layer whose refractivity index is substantially equal to that of the liquid crystal layer, another highly reflective mirror, another transparent electrode layer, and another glass substrate, which are stacked in this order. An etalon cavity of the filter includes two layers, the liquid crystal layer and the transparent material layer (such as a glass plate), which enables the cavity length to be increased without increasing absorption and scattering of the cavity. This makes it possible to narrow the FWHM, quicken the response time, and increase the transmittance of the filter. Applications for the filter include a double cavity structure tunable wavelength-selective filter of a wide tunable range, and a photodetector of a simple construction.

摘要： A technique for electrically mounting a surface-normal optical device or material on a waveguide-type optical device while the characteristics of the mounted device are effectively used is disclosed. The waveguide-type optical device comprises a substrate on which optical waveguides or fibers are provided and a trench is formed; a pair of electrodes which is assigned to each optical waveguide or fiber and is formed from the surface of the substrate to wall surfaces of the trench; and a material or device which is filled or inserted into the trench, and which has an electro-optic effect, thermo-optic effect, light emitting function, light receiving function, or light modulating function. Another type of device comprises a thin and surface-normal active optical device driven by an applied voltage, which is substantially vertically inserted into the trench and is fixed in the trench; and a support member attached to the inserted device.

摘要： The optical beam emitted from the transmitter array is input into the polarization beam splitter, and then turned by a right angle to input the opening portion of the neighboring board. Then, polarization of the optical beam is controlled by the polarization control array device provided on the opening portion to thereby rotate a plane of polarization by 90.degree., then the optical beam is turned by the polarization beam splitter by a right angle to input into the first light deflection control array device which then controls the propagation direction of the optical beam to input into the desired photodetector. On the other hand, the optical beam whose plane of polarization is not rotated by the polarization control array device by 90.degree. passes through the polarization beam splitter along the propagation direction to input into the opening portion of the neighboring board, and is then controlled similarly. The optical beam array emitted from the transmitter array with the lens array which is attached to the lower end portion of the board is received by the light deflection control array device, then the propagation direction of the optical beam array is variably controlled every optical beam to be input into the mirror with a gradient, and then the optical beam array reflected by the mirror is received by the photodetector with the lens array. Therefore, the optical beams from the desired boards can be connected to the photodetector mounted on another desired board. Similarly, the board-to-board free-space optical interconnection system between the boards in a certain unit and a different unit arbitrarily can be provided by introducing the light deflection control array device.
