Ultra-compact multichannel optical components based on PLC technologies

Study of carrier injection for performance optimization of a reconfigurable waveguide digital optical switch on InGaAsP/InP

“…Another design comprises waveguides th a t can be re-positioned to allow evanescent coupling to an adjacent waveguide, similar to a directional coupler [22]. Yet other designs involve the insertion of MEMS mirrors into the optical p ath of Y-or X -splitter switches [23,24]. Such waveguide-based designs are much more compact th an the free-space designs using mirrors, and they also switch more quickly (on the order of ps) because of the smaller translational distances required.…”
