Compact 64x64 Micromechanical Optical Crossconnect

This paper describes a 64x64 beam steering optical crossconnect constructed using surface micromachined mirrors. It used a curved mirror as a Fourier transform element and to fold the optical system. Both MEMS mirrors arrays are fabricated on a single chip and packaged in a single package. The switch fabric size, at 100x120x20mm, is compatible with mounting on a standard circuit card. The crossconnect achieves a mean fiber-to-fiber insertion loss of 1.9dB.
