Crosstalk Reduction in a Shallow-Etched Silicon Nanowire AWG |
| |
Abstract: | We introduced shallow-etched silicon nanowire into the arrayed waveguides to decrease the random phase error due to the core width fluctuation. A fairly improved crosstalk value of 18 dB was achieved in the fabricated arrayed-waveguide grating with the on-chip loss of 3 dB. |
