摘要： An optical space switch is formed in such a manner that switch elements having two inputs and two outputs are arranged in an n.times.n matrix form and optical signals from n input highways are switched to n output highways. The switch elements are connected in such a manner that the optical signals are always passed through the same number of switch elements, from the input highways to the output highways.

摘要： A method for fabricating an SHG device by forming an inversion region having a first direction of polarization selectively in a ferroelectric substrate that has a second, opposite direction of polarization. A proton exchange process exchanges cations in the ferroelectric substrate with protons, selectively in correspondence to each portion of the substrate in which an inversion region is to be formed. Electrodes are provided on upper and lower major surfaces of the ferroelectric substrate, and the inversion region is selectively grown in a direction perpendicular to the upper major surface of the ferroelectric substrate while applying a d.c. voltage to the electrode on the upper major surface of the ferroelectric substrate thereby to induce an electric field acting in a direction coincident with the direction of said first polarization in said ferroelectric substrate.

摘要： An optical switch comprising: an electrode-optic crystal substrate (1, 1'); a central waveguide (21); a pair of input waveguides (22, 23), and a pair of output waveguides (24, 25). A refractive-index-changed region (R') is provided symmetrically within some part of the central waveguide. Switching from the straight-through state to the branching state or vice versa is carried out by introducing a change in the refractive index of the index-changed region.

摘要： An optical beam profile transforming element which is a monolith solid element with a low loss is provided by placing at least two parallel plastic wave guide layers in contact with each other, each of the at least two parallel plastic wave guide layers having a refractive index gradually varying in the direction of light propagation so that the at least two parallel plastic wave guide layers as a whole transform a profile of an optical beam in the direction vertical to the layers. The variation of the refractive index can be obtained by varying a concentration of a dopant in a matrix, and the variation of the concentration of a dopant in a matrix can be obtained by varying an irradiation amount of a combination of a matrix and a dopant monomer with an ultra-violet ray.
