Abstract
All-optical power discrimination at lambda = 1.5 mu m is demonstrated for r epetition frequencies > 10GHz by using a saturable absorber vertical cavity device, Measurements on modulated signals reveal a modulation contrast enh ancement by a factor of four after reflection on the device. The ultrafast absorber response is obtained by heavy-ion irradiation of the absorbing lay ers. Frequency performances beyond 100GHz can be further foreseen with this technique.
