Tunable Superconducting Split Ring Resonators

Tunable ring resonators for silicon Raman laser and amplifier applications

Recently, low threshold Raman silicon lasers based on ring resonator architecture have been demonstrated. One of the key elements of the laser cavity is the directional coupler that couples both pump and signal light in and out of the ring resonator from the bus waveguide. The coupling coefficients are crucial for achieving desired laser performance. In this paper, we report design, fabrication...

Wavelength Tunable Laser with Silica-Waveguide Ring Resonators

We have proposed a tunable laser with silica-waveguide ring resonators. In this tunable laser, a semiconductor optical amplifier was passively aligned and mounted onto a silica-waveguide substrate. The ring resonators can be tuned by controlling their temperatures using the thermo optic heaters formed on them, and there are no mechanically moving parts. Thus, they are sufficiently stable and re...
