Abstract :
In this work, we present the first demonstration of optical label swapping using an RSOA. Specifically, we exploit the high pass filter (HPF) behavior originating from self-gain modulation (SGM) of the saturated RSOA to achieve simultaneous erasure and rewriting of an amplitude-shift-keying (ASK) label. We demonstrate the feasibility of a 1.25 Gb/s amplitude-shift-keying (ASK) label erasure with new label rewrite through direct modulation of the RSOA
