Sub 10 ps photocarrier response time in an electroabsoption modulator using a custom epitaxy structure is demonstrated. This design used quantum well offsetting, carbon doping, and valence band discontinuity minimization, to achieve a 3.5 ps response

High speed cross-amplitude modulation in concatenated SOA-EAM-SOA

Autor: C. S. Cleary, Robert J. Manning

Publikováno v: Optics express. 20(13)

We observe a near-ideal high speed amplitude impulse response in an SOA-EAM-SOA configuration under optimum conditions. Full amplitude recovery times as low as 10 ps with modulation depths of 70% were observed in pump-probe measurements. System behav

We experimentally demonstrate 80 Gbit/s wavelength conversion to two copies by simultaneously extracting the blue- and red-shifted sidebands from XPM in a silicon nanowire. Bit error rates of 10-9 with only ~2 dB power penalty is achieved for both si

Fast gain recovery rates with strong wavelength dependence in a non-linear SOA

Autor: C. S. Cleary, Robert J. Manning, Mark Power, Roderick P. Webb, Simon Schneider

Publikováno v: Optics express. 18(25)

We report remarkably fast and strongly wavelength-dependent gain recovery in a single SOA without the aid of an offset filter. Full gain recovery times as short as 9 ps were observed in pump-probe measurements when pumping to the blue wavelength side
