Compact design of an optical phase shifter packaged with IST microheater used for integrated photonics

A design of compact optical phase shifter which is constructed by two cascading microring resonators and a corresponding packaged microheater is proposed. We illustrated that the footprint of the compact phase shifter could be within 25um × 10um. The effective index change efficiency under thermo-op...

The effective index change efficiency under thermo-optic effect is significantly increased and the thermal distribution is highly concentrated.
