Abstract: An optical transmitter may generate a first optical signal having a first wavelength and a second optical signal having a second wavelength. The optical transmitter may output the first and second optical signals to a link without performing a multiplexing operation. The optical transmitter may output part of the first optical signal to the link while part of the second optical signal is being output to the link. An optical receiver may receive the first and second optical signals, via the link, as separate optical signals. The optical receiver may receive part of the first optical signal from the link while part of the second optical signal is being received from the link. The optical receiver may provide the first and second optical signals to a photodetector array that includes a first photodetector to detect the first optical signal and a second photodetector to detect the second optical signal.

Abstract: An optical coupling system includes an optical signal source to provide an optical signal from an aperture. The system also includes a substantially planar high-contrast grating (HCG) lens to convert an optical mode of the optical signal to provide a converted optical signal having a mode-isolating intensity profile. The system further includes an optical element to receive the converted optical signal. The optical signal source and the substantially planar HCG lens can be arranged to substantially mitigate coupling of a reflected optical signal associated with the converted optical signal that is reflected from the optical element to the aperture of the optical signal source based on a reflected mode-isolating intensity profile.
