We propose a novel optical time-to-live (TTL) processing scheme using asymmetric Mech-Zehnder interferometer (AMZI) and Fabry-Perot semiconductor optical amplifier (FP-SOA). AMZI transfers M TTL pulses into M-1 pulses and two residual pulses with 6-dB power difference. FP-SOA enhances the power difference between the M-1 pulses to the residual pulses to more than 10 dB. A numerical model is established for verifying the feasibility of this scheme.

AMZI transfers M TTL pulses into M-1 pulses and two residual (AMI) and Fabry-Perot semiconductor optical amplifiers (FP-SOA) pulses with 6-dB power difference. FP-SOA enhances the power difference between the M-1 pulses to the residual pulses to more than 10 dB. A numerical model is established for verifying the feasibility of this scheme.
