Abstract

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, and characterization of tunable silicon ring resonators for Raman laser and amplifier applications. By employing a tunable coupler, the coupling coefficients for both pump and signal wavelength can be tailored to their optimal values after the fabrication, which significantly increases the processing tolerance and improves the device performance.
