OPTICAL COUPLER FOR INTEGRATED CIRCUITS PROVIDED WITH OPTICAL WAVEGUIDE

摘要

The invention relates to an integrated circuit comprising a semiconductive layer (3) which is formed with an insulating interface (2) above a substrate (1) comprising an optical waveguide consisting of the strip (5) of the semiconductive layer. Said integrated circuit also comprises a lateral coupler for introducing light which is provided with an insulating material strip (6) whose thickness is higher than the diameter of an incident laser beam and which covers the semiconductive strip. An array structure (11) is formed in the semiconductive ribbon in an orthogonal direction with respect to a direction of light propagation to the interface with the insulating material strip.
