The investigation, modeling, and improvement of the thermal response of CMOS-compatible modulators based on micro-ring resonators

A ring resonator is a waveguide that circles around to make a closed usually circle-shaped loop. The electromagnetic wave may travel within this loop and instructively interfere with itself if the travel length is a multiplicative of the wavelength of the wave. In such a situation, energy builds up in the ring and very strong resonances are achievable. There is usually one or two bus waveguides that let the light couple into and out of the ring resonator. The resonance of the ring demonstrate themselves as sharp dips in the spectrum of the bus waveguide(s) output. People found ways to modify the resonance wavelength of the ring and, as a result, the position of these dips by injection/extraction of charge carriers into the ring body and make very efficient CMOs-compatible modulators. We are planning to study the thermal and aging effects on the performance of such modulators.
