Paper Abstract

This paper describes a novel design for a variable optical delay line (ODL) based on modified version of a recently developed MEMS-based 3-D rotating inclined micromirror (3DRIM). The 3DRIM is created by assembling a micromirror onto the top of a rotary comb-drive motor. The comb-drive motor is able to achieve a few degrees of rotation. The new ODL architecture uses two such 3DRIMs located inside a rectangular cavity with mirrored walls. Light from an input fiber is redirected by the 3DRIMs, and caused to reflect within the cavity a number of times, depending on the rotational angle of the 3DRIMs. In this way, the ODL can achieve variable optical delays of up to 3.7 nsec.
