It is long), entered by condenser lens coupling 210 in AWG demultiplexers 220, (such as 4 waveguides) difference in corresponding output waveguide
Output, is then coupled on corresponding reception PD or PD arrays 240 by single lens or lens array 230, by overstating that resistance is put
Big device TIA 250 exports electric signal after amplifying, and completes the reception of optical signal.Or in turn, laser driver LDD 250 drives
The laser 240 of 4 wavelength sends lightwave signal, is coupled into by condenser lens 230 in the corresponding waveguides of AWG 220, by AWG
Fiber adapter 205 is coupled into by lens 210 again after multiplex, this method has higher than foregoing TFF types WDM demultiplexers
Integrated level, but fiber adapter 205, condenser lens 210, AWG 220, condenser lens (or focusing lens array) 230 and PD (or
PD arrays) between need linkage to adjust, variable element is too many, inefficiency, to actual manufacture bring very big puzzlement with it is difficult.
