Arrayed waveguide grating optical multiplexer/demultiplexer |
摘要 |
<p>An arrayed waveguide grating optical multiplexer/demultiplexer includes an arrayed waveguide connected to at least one first optical waveguide via a first slab waveguide. A plurality of second optical waveguides are connected to the arrayed waveguide via the second slab waveguide. A number (Nch) of the plurality of second optical waveguides is determined to substantially satisfy the equation, DELTA ffsr = DELTA fch . Nch. DELTA ffsr is Free Spectral Range of the arrayed waveguide grating optical multiplexer/demultiplexer. DELTA fch is a frequency interval between frequencies of lights to be input to the arrayed waveguide grating optical multiplexer/demultiplexer for being multiplexed or lights to be output from the arrayed waveguide grating optical multiplexer/demultiplexer after being demultiplexed. <IMAGE></p> |
