Wide bandwidth, low loss 1 by 4 wavelength division multiplexer on silicon for optical interconnects

We demonstrate an add/drop filter based on coupled vertical gratings on silicon. The concept is extended to implement a 1 by 4 wavelength division multiplexer with 3nm bandwidth, 1dB insertion loss and 16dB crosstalk suppression.
