Thermo-Optical Tuning Cascaded Double Ring Sensor with Large Measurement Range

Thermo-Optical Tuning Cascaded Double Ring Sensor with Large Measurement Range

In this paper, a thermo-optic tuning optical waveguide sensor system based on a cascaded double micro-ring resonator is investigated. The system consists of a micro-ring resonator with the microheater as a reference ring and a micro-ring resonator with removing the upper cladding layers as a sensing...
