We report a free space optical (FSO) communication system for bi-directional passive optical network (PON) based on a MEMS spatial light modulator (SLM). A piezoelectric PZT scanner is used to display a marker image to invite a passive optical terminal (POT) and to keep the optical link even when the POT moves. Unlike wireless network that broadcasts radio signals, the FSO system in this work provides...
In this paper, we report a two-dimensional MEMS optical scanner that actuate and detect the angular motion through the piezoelectric effect of thin film PZT. Typical scan ranges were ±12° at 25 kHz for the horizontal resonance and ±8° at 60 Hz for the vertical non-resonance, and the overall power consumption was 100 mW or less. A newly designed mechanical rib structure on the backside of the mirror...
We present an electrostatic vertical comb-drive MEMS optical scanner with the angle magnifier mechanism developed for a 140-kHz wavelength tunable-laser in the swept-source OCT system of a 2 ms/frame visualization capability.
