Experimental demonstrations of ring resonators with TiO2 cores are presented and measured with −2.9pm/K resonance shift. Their thermo-stress-optic behavior was found to be important to their function; therefore an inclusive model is presented and simulated numerically.
A comprehensive investigation of silicon microring sensor, which is used for temperature detection, is reported in this paper, and the theory was introduced in detail. Numerical analysis shows that the silicon microring has a high sensitivity and a very good linearity between real-time temperature and effective index. By optimizing the parameters, the microring sensor can obtain a higher sensitivity...
Owing to the negative thermo-optic coefficient (TOC) of titanium dioxide, the real effective modal index of Cu-TiO2-Si hybrid plasmonic waveguides can be potentially temperature independent. High-performance Cu-TiO2-Si waveguide-ring resonators (WRRs) are experimentally demonstrated on SOI platform using standard CMOS technology. TOC of the group index is measured to be ~1.09×10-4 K-1 for a WRR with...
