REALIZATION OF 16 GB/S ALL-OPTICAL TOGGLE MEMORY UTILIZING CHANGE IN POLARIZATION STATE OF LIGHT IN BIDIRECTIONAL OPTICAL FIBER

Abstract:

In this investigation all-optical Toggle flip-flop event-driven memory is explored with data rate of 16 Gb/s. Bidirectional optical fiber is used as a nonlinear medium to generate the output set and reset pulses of a toggle flip-flop, the model is built using the bidirectional optical principle, taking into account the fundamental effects of cross phase modulation and self-phase modulation with change in polarization state. The performance of a flip-flop is evaluated using truth table conditions and performance parameters such as Q factor, which is obtained as 380.92 dB for Q and 272. 9 dB for Q?, rising and falling times of 7.304 ps and 5.79 ps, respectively, is obtained which makes flip-flop design fast.
