Optical intensity division multiplexing method having demultiplexed signal 45 degrees polarisation to the principal propagation axis and with an intensity adapted ensuring soliton mode placement at the filter.

摘要

The optical demultiplexer has a multiplexed intensity optical signal with injection with the demultiplexer signal injected (2) into a birefringent propagation region (3). There is a frequency filter output (4). The injection system inputs a 45 degree polarisation to the principal propagation axis and with an adapted intensity ensuring soliton mode placement at the filter.
