All-Optical Header Processing using Direct Modulation of a Fabry-Perot Laser Diode for All-Optical Packet Switching

Abstract

In this paper, all-optical header processing using an injection-locked Fabry-Perot laser diode (FP-LD) for all-optical packet switching is demonstrated. Optical packets consisting of the 1.25 Gb/s optical header and the 10 Gb/s payload are put into the FP-LD of which amplitude is modulated by a control signal. When the header bit coincides with the trigger of the control, the FP-LD is injection-locked signal and the FP-LD outputs a switched-on optical signal. Otherwise, the FP-LD outputs a switched-off optical signal of which the payload is suppressed.
