Experimental Demonstration of Optically Determined Solar Cell Current Transport Efficiency Map
Amaury Delamarre, Laurent Lombez, Kentaroh Watanabe +3
A recently suggested reciprocity relation states that the current transport efficiency from the junction to the cell terminal can be determined by differentiating luminescence imag…
Ultra-broadband surface-normal coherent optical receiver with nanometallic polarizers
Go Soma, Warakorn Yanwachirakul, Toshiki Miyazaki +8
A coherent receiver that can demodulate high-speed in-phase and quadrature signals of light is an essential component for optical communication, interconnects, imaging, and computi…
Non-redundant optical phased array
Taichiro Fukui, Ryota Tanomura, Kento Komatsu +4
