Development and characterization of micro-mechanical gratings for optical modulation

Abstract

Two types of micro-electro-mechanical gratings have been designed for use as optical modulators. The gratings have been fabricated and experimentally characterized, yielding excellent results. Micro-electro-mechanical gratings are possible candidates for applications such as intra-cavity switches for Q-switched lasers, or intensity modulating switches for free-space optical interconnects. Compared to commercially available acousto-optic modulators, micro-electro-mechanical gratings are smaller, weigh less, and can be manufactured in large quantities for a fraction of the cost.
