All-optical one-bit latch with phase encoded data using phase information processing through four wave mixing in semiconductor optical amplifier

摘要

In this report, we have proposed a simple new scheme of all-optical one-bit latch with phase encoded data using the property of phase information processing of self-pumped intraband ultrafast four wave mixing in semiconductor optical amplifier. This latch unit can store a single bit of information given at the input and maintain this information even when the input is withdrawn. To change the data stored at the output of the latch, the input data should be changed accordingly.
