Embodiment Construction
[0050] TeO converted from o-light to e-light 2 AOTF can realize the requirements of smaller line width, polarization maintenance and higher diffraction efficiency as an OADM device. figure 2 It is a schematic diagram of the system structure, and its working mechanism has both similarities and differences with the integrated AOTF. After the polarizing beam splitter PBS divides the incident light into o light and e light, the o light enters the TeO above in one optical path 2 AOTF (13), realizes filtering and mode conversion; another way enters the polarization converter (11) with e light, converts e light into o light, and then enters the following TeO with the same performance 2 AOTF (13) realizes filtering and mode conversion equally; The filtering signal (14) that comes out from two AOTFs (13) is e light, and 3dB coupler (16) respectively two-way filtering signal and two-way non-filtering long signal ( 15) Drop off or continue transmission after merging. In addition, the...
