A high-speed optical star network using TDMA and all-optical demultiplexing techniques [PDF]

, 1996
The authors demonstrate the use of time-division multiplexing (TDM) to realize a high capacity optical star network. The fundamental element of the demonstration network is a 10 ps, wavelength tunable, low jitter, pulse source. Electrical data is encoded

Solid and hollow whispering gallery mode resonators for all optical switch [PDF]

EPJ Web of Conferences
Whispering-gallery-modes resonators (WGMR) are effective switching devices when either coated or filled with non-linear material. We present examples of all-optical switching of hybrid WGM using polyfluorene, a methacrylate azobenzene and an acrylate ...
