Power Insensitive Silicon Microring Resonators Lian-Wee Luo, Gustavo S. Wiederhecker, Kyle Preston, and Michal Lipson http://dx.doi.org/10.1364/OL.37.000590 We demonstrate power insensitive silicon microring resonators without the need for active feedback control. The passive control of the resonance is achieved by utilizing the compensation of two counteracting processes, free carrier dispersion blueshift and thermo-optic redshift. In the …
