Sensitive birefringent temperature sensor based on a waveguide ring resonator.
A sensitive birefringent thermometer based on a SiO2 waveguide ring resonator is demonstrated in this paper. It can be used to fabricate a terahertz thermal detector. The temperature sensitivity is enhanced by the resonances of two polarization modes in the waveguide ring resonator. A high degree of common rejection exists for external influence. A linear temperature range from 6°C to 40°C has been detected with resolution of 0.025°C.
