GaInAsP/InP waveguide dual core spot size converter for optical fiber
IEEE Photonic Society 24th Annual Meeting, 2011•ieeexplore.ieee.org
… INTRODUCTION When we connect optical fibers to III-V compound semiconductor
optical waveguides, we have to pay much attention to reducing the coupling losses caused
by the mismatch of spot size between optical fibers and semiconductor waveguides having
rather high index contrast. Introducing a spot size converter (SSC) in the end facet of the
optical waveguide is effective to reduce the coupling loss. … In order to reduce a coupling
loss between a semiconductor optical waveguide and an optical fiber, we developed the …

A dual core spot size converter was developed for reducing a coupling loss between an optical fiber and a III-V compound semiconductor optical waveguide. It can be fabricated without a crystal regrowth process.
