Abstract

In this paper we describe a novel switch architecture for single-mode optical fibers based on micromirror arrays. This architecture allows scaling to a large number of fiber ports and can be integrated directly with free-space wavelength multiplexers (gratings). Using tilt-up surface micromachined polysilicon micromirrors, a 2×2 switch configuration was demonstrated. The measured insertion loss was -4.2 dB and the cross-talk was −50 dB. The mirrors used in the switch design have a maximum optical deflection of 24 degrees and a resonant frequency of 1.9 kHz, leading to a switching time (including settling) of 2 ms. The micromirrors have sufficient resolution to support scaling to 19 channels while maintaining the same low cross-talk.
