Abstract: Optical intelligent reflecting surface (OIRS) offers a new and effective approach to resolving the line-of-sight blockage issue in visible light communication (VLC) by enabling redirection ...
The same optic fibers that pulse with the world’s Internet traffic are now listening to the pulse of the planet, picking up earthquake tremors in better detail than traditional seismic networks do. In ...
Abstract: We demonstrate a new method to achieve high-power and wavelength flexible broadband light based on a random fiber laser (RFL)-pumped Raman amplifier seeded by a superluminescent diode (SLD).
