Low-thermal-resistance by Decoupled Ridge Insulation Structure for hybrid GaInAsP/SOI ridge-waveguide lasers

Abstract

Low-thermal-resistance hybrid GaInAsP/SOI ridge-waveguide Fabry-Perot lasers were demonstrated. Novel ridge-insulation structure was introduced to enhance heat dissipation. Record low thermal resistance of 14.3 K/W were demonstrated at 2-mm-cavity length even on SOI with $3.0-\mu \mathrm{m}$-thick oxide layer.
