Abstract (en)
[origin: CN110785686A] Methods and systems for a free space CWDM MUX/DEMUX for integration with a grating coupler based silicon platform may include an optical assembly comprising a lens array and a plurality of thin film filter splitters having angled reflective surfaces. The optical assembly may be operable to receive an input optical signal comprising a plurality of optical signals at different wavelengths via an optical fiber, focus the input optical signal onto a first thin film filter splitter, reflect a first of the optical signals into the lens array and passing others to a second thin film filter splitter,and reflect a second optical signal into the lens array and passing others to a third of the plurality of thin film filter splitters.
