Title: Semiconductor optical component comprising a spot-size converter

Abstract: A semiconductor optical component, comprising a spot-size converter to deconfine the optical mode, comprises an active waveguide and a passive waveguide that are superimposed and buried in a sheathing layer. The component successively comprises a damped coupling section in which the width of the active waveguide tapers down and the width of the passive waveguide increases, and a mode expansion section comprising only the passive waveguide whose width tapers down.
