文摘

We propose and experimentally demonstrated a thermally tunable ring reflector, which is made up of a Y-branch splitter and ring resonator on SOI platform using a CMOS-photonics technology. The results show good reflectivity which can up to be 90?% near the 1550?nm. The reflective response is successfully tuned by one free spectral range through thermo-optic effect with a tuning efficiency of 5.3?mW/nm. We also discuss its applications in silicon hybrid lasers.
