We demonstrate the WDM transmission over 1280-km SSMF with four 1.875-Tb/s superchannels, which is the highest bit rate per superchannel among those WDM reports using NGI-CO-OFDM. The BERs of all the four superchannels are below 3.8×10-3 after transmission.

We present amorphous silicon solar cells on random and periodic back reflector geometries. 1D gratings offer an intuitive understanding of the light trapping process by excitation of guided modes. Using the same period and similar shape, better performance is observed on 2D gratings due to a higher number of resonances.
