Experiments on Optoelectronic Bistability in Distributed AIAs/GaAs-Bragg Reflectors

We present measurements of optoelectronic bistability in hybrid distributed AlAs/GaAs Bragg reflectors. A threshold optical input power of 40 μW is observed leading to an estimated switching energy of 0.1 fJμm-2 Using voltage shift of 60 V and an optical input power of 100 nW. an electroptical modulation of 40 % is obtained.
