Design of athermal all-polymer waveguide microring resonator*

Abstract

The athermal all-polymer waveguide microring resonator is realized by selecting polymer substrate with proper thermal expansion coefficient to substitute the silicon one. The designed results show that the maximal resonant wavelength shift is −0.0085nm and the maximal temperature dependent wavelength shift slope is −0.0009nm/K when the temperature varies from 20°C to 65°C.
