Abstract

We investigate the thermo-optic effects on second harmonic generation (SHG) in AlGaAs/AlO(x) microring (MR) waveguides. We show that SHG can be utilized to enhance the thermal sensitivity of MRs. This sensitivity makes this structure appropriate for thermal modulation and switching of optical signals or temperature sensing.
