Integrated optics


An optical circuit with integrated optic components such as light emitter, photodetector, modifier, and optical waveguide.

Optical circuits are created by IC fabrication process, especially the multilayer thin film deposition technique including insulation layer, or silicon on insulator (SOI). The existing optics system converts optical signal to electrical signal, and converts again to the optical signal after electrical signal processing. However, the integrated optics device performs the signal processing directly in the optical integrated circuit, thereby making drastic size and weight reduction, power saving, and increasing processing speed.
