Popis: In the present scenario of all-optical communication, the design of the optical switch, optical router, optical synchronization, reference clock, optical latches, etc., becomes very essential. Moreover, the matched, combined operation of all these optical components with the existing network is also necessary. In these fields, semiconductor optical amplifier (SOA) technology is very suitable, because of its high-speed switching capacity, as well as good amplification factor, high extinction ratio and high integration potential. SOA does the entire processing in optical domain, without any electronic conversion, including all-optical wavelength conversion, wavelength separation, regeneration, frequency encoding with in-line amplification, in optical domain (photon-level interaction). In this paper, a noble idea on the all-optical D flip-flop and T flip-flop using SOA is proposed.
