All-optical discrimination at 1.5 /spl mu/m using ultrafast saturable absorber vertical cavity device

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