OPTICAL MODES WAVE-GUIDE CONTROLLED CONVERTER Russian patent published in 1995 - IPC

FIELD: data optical processing; integral optics; fiber-optic communication lines. SUBSTANCE: optical substrate with optical wave-guide is used in the device. There are two pairs of metal electrodes, which have interelectrode spaces be aligned with optical input and optical output. Electro-optic transparent layer has refractivity being higher than refractivity of optical waveguide. The layer is disposed onto the surface of optical waveguide above the first and the second metal electrodes under cover layer. The transparent layer has to be rectangular parallelepiped, which is truncated by the plane, which forms straight line when crossing with top plane of optical waveguide. The straight line is perpendicular to the direction of propagation of optical coherent radiation. EFFECT: improved efficiency of operation; improved reliability. 2 cl, 10 dwg
