New Ground-to-Train High-Speed Free-Space Optical Communication System with Fast Handover Mechanism
Free-space optical communication Scanners
2015/5/26
We developed a new ground-to-train free-space optical communication system that performs stable high-speed communication even when a train is running at high speed and does fast handover between laser...
Characterization of a MEMS Based Optical System for Free-Space Board-to-Board Optical Interconnects
Free-space optical communication Alignment
2015/6/9
We demonstrate alignment of an array of VCSELs to detectors, using a MEMS-based lens system for free-space board-to-board optical interconnects. Our optical system is capable of aligning up to 5 degre...
Wave-vector space picture for radiationless focusing and beaming
Wave-vector space picture radiationless focusing beaming
2015/8/10
Radiationless interference of an electromagnetic wave occurs in the near field when the feature sizes of the waves are at the deep subwavelength scale. We present the propagation in such a regim...
