Abstract:
We demonstrate a bulk silicon alternative to the conventional silicon-on-insulator photonics platform, using common CMOS process-based Si(3)N(4) masking and oxidation techniques. We show waveguide losses as low as 2.92 dB/cm with a technique that can be implemented on the front-end of a typical CMOS fabrication line.
