A method for accurately and quickly bonding a planar lightwaveguide circuit (PLC) and a laser diode is proposed. It is based on simultaneous auto-focusing on marks fabricated on the PLC and laser diode. Bonding equipment constructed to implement the method achieves alignment accuracy of ± 1 μm and greatly reduces the turn-around-time, i.e., the time from when the laser diode is picked up by the tweezers to completion of the bonding process.

A large-scale, compact optical switch based on MEMS-tilt mirror arrays and free-space optics is described. The mirror fabricated by the SOI-bulk micromachining technology provides reliable switching, and the optics consists of low-cost, high-accurate polymer components. A prototype with 100-ch I/Os features a coupling loss of 4.0dB and switching time of 3ms.
