Paper Abstract

Impacts of walk-off, initial time delay and peak power of control pulse on the characteristics of NOLM de-multiplexer are studied in this paper. Walk-off between control pulse and signal pulse makes the NOLM de-multiplexer switching window deviate from the center position, and the transmittance also be decreased. It is researched that for a given walkoff, there is a critical value of initial time delay and peak power of control pulse respectively which ensures the switching window profile relocates at the center and the switching efficiency is 1. To take Gaussian pulse shape for example, for a given walk-off d, the switching window can be relocated at the center position by setting the initial time delay Td = -Ld/2 between control and signal pulse.
