The effects of amplified spontaneous emission (ASE) and the input pulse energy on the system’s quality factor are studied. For the parameters used, the all-optical logic gates using SOAs are capable of operating at speed of 80 Gbit/s. Hits: 4122 Download times: 657 View Full Text    Download reader
