Simultaneous optimization of confinement and thermal performance for heteroepitaxial InP on SoI hybrid lasers

Abstract : In new designs permitted by heteroepitaxial bonding of III-V active slabs onto nano-patterened SoI wafers, two constraints arise in the design: optical confinement and thermal performance. One require less silicon for the former and more silicon for the latter. We propose a mitigation strategy based on electromagnetism and a flip-flop algorithm.
