Abstract： |
The invention belongs to high-speed optical communication field, relating to an optical-fiber time division multiplexer device keeping each-path polarizing state the same, including an optical-fiber coupler, two ports on one side of which are input and output ends respectively, and its character: it also includes an optical isolator, two optical-fiber segments and two Faraday rotating mirror; where one side of the coupler is connected with the input end, and the two ports are connected with the rotating mirror through the two optical-fiber segments, respectively. On the condition of ordinary single-mode optical fiber, it can completely compensate optical-fiber birefraction, inherent or caused by the outside world, achieving the effect of keeping each-path polarization the same. |
