Mid-infrared wavelength multiplexers on an InP platform [PDF]
NanophotonicsWe demonstrate mid-infrared multiplexers based on evanescent couplers in In0.53Ga0.47As/InP ridge waveguides. Multiplexing of λ = 5.2 µm and λ = 8 µm input wavelengths in TM00 modes to a single TM00 output was achieved with 0.7 dB insertion loss.

Effect of mask discretization on performance of silicon arrayed waveguide gratings [PDF]
, 2014 We studied the impact of the lithography mask discretization on silicon arrayed waveguide grating (AWG) performance. When we decreased the mask grid from 5 to 1 nm, we observed an experimental improvement in crosstalk of 2.7-6 dB and cumulative crosstalk
