Abstract
In this paper we introduce a MEMS scanner with a monolithic silicon 2-D photonic crystal (PC) mirror with broad-band high reflectivity (>90%) in the 1550 nm wavelength band. The photonic crystal is generated as an integrated part of the MEMS scanner fabrication process, resulting in a monolithic structure with a mirror that is ultra-flat with ~lambda/100 flatness over a 500 mum times 500 mum area. The reflectance spectrum shows that the PC mirror has a high reflectivity (>90%) band from 1520 nm-1620 nm. The scanner has a scan range of 22 degrees at an input square wave of 67 V with a resonance frequency of 2.13 kHz.
