It is long), entered by condenser lens coupling 210 in AWG demultiplexers 220, in corresponding output waveguide (such as 4 waveguides) point
Do not export, be then coupled to by single lens or lens array 230 on corresponding reception PD or PD arrays 240, by overstating resistance
Amplifier TIA 250 exports electric signal after amplifying, and completes the reception of optical signal.Or in turn, laser driver LDD 250
The laser 240 of 4 wavelength of driving sends lightwave signal, in the waveguide as corresponding to condenser lens 230 is coupled into AWG 220,
Fiber adapter 205 is coupled into by lens 210 again after AWG multiplex, this method has than foregoing TFF types WDM demultiplexers
Higher integrated level, but fiber adapter 205, condenser lens 210, AWG 220, condenser lens (or focusing lens array) 230
Linkage is needed to adjust between PD (or PD arrays), variable element is too many, and efficiency is low, and very big puzzlement is brought to actual manufacture
