| Abstract(in English) | We describe a large-scale optical switching fabric based on Risley optical-beam deflectors and free-space optics. The Risley deflector consists of two wedge-shaped prisms and precisely controllable rotation mechanisms ; an optical beam can be deflected to the direction of two axes by rotating each prism independently. The deflectors potentially have a self-latching function, which provides a reliable switching operation, and a large-deflection angle over than 15 deg., which makes the switch compact. We experimentally confirmed that prototype switch modules (hardware volume : 15×15×31mm, deflection angle : <18 deg.) have a scalability of the switch up to 256 ports, low-loss characteristics of 1.0-1.5dB, and switching time of within 6 sec. |
