A fully packaged 4/spl times/4 integrated optical switch matrix

This paper describes a packaged and fiber array coupled 4/spl times/4 optical crosspoint switch designed for optical packet switching. Alignment and fixation techniques of two perpendicular fiber arrays to the integrated InP-based switch chip have been developed. Thermal management is also included in the packaging. The packaged devices demonstrate long-term stability and have been used in switch modules, including the packaged device and electronic interfaces.
