Ie. Day et al., LOW-POWER ALL-OPTICAL POLARIZATION GATE SWITCH IN A PASSIVE INGAASP MQW WAVE-GUIDE AT 1.53-MU-M, Electronics Letters, 30(13), 1994, pp. 1050-1051
Optimised design of an InGaAsP multiquantum well waveguide has allowed
the demonstration of all-optical switching of a 30ps pulse with coupl
ed peak powers of 350mW. This is achieved at 1.53mum using resonant ba
ndfilling and plasma effect refractive nonlinearities.
