Abstract:
A microelectromechanical system (MEMS)-based 238 x 238 micromachined optical crossconnect switch was discussed. The switch utilizes surface micromachined two-axis tilt mirrors which exhibit a curvature-induced loss of < 0.3 dB. Two fiber arrays with attached collimating microlenses were used to project and receive beams from two 2-dimensional arrays of two-axis electrostatic micromirrors. The mean fiber-to-fiber insertion loss of the fabric was found to be 1.33 dB and the maximum insertion loss to be 2 dB.
