High power, high SMSR and wide tuning range silicon micro-ring tunable laser.

An external cavity tunable laser, which is based on a silicon hybrid micro-ring resonator, is demonstrated. The heat isolate grooves around the rings effectively cuts off temperature crosstalk. Experimental results have shown that the output power of this device can reach 15.

Silicon micro-ring tunable laser for coherent optical communication.

A compact external cavity tunable laser based on a silicon hybrid micro-ring resonator is demonstrated. A theoretical model is also employed for design and analysis of the wavelength tuning performance of the device. In this model, the gain section of the device is simulated by a conventional multimode rate equation model, whereas all rest passive sections are modeled by the frequency domain method.
