LCD is entering virtual reality

Virtual reality (VR) is an emerging wearable display technology with potential applications for entertainment, education, training, design, advertisement, and medical diagnostics. Both liquid crystal display (LCD) and organic light-emitting diode (OLED) are applicable for such head-mounted displays. Currently, OLED is

Physics World: “Deep learning improves fibre optic imaging”

A paper titled “Deep Learning Imaging through Fully-Flexible Glass-Air Disordered Fiber” by Professors Amezcua, Pang, and Schülzgen is featured in Physics World. We demonstrate a fully flexible, artifact-free, and lensless fiber-based imaging system. For the first time, this system combines image reconstruction by a trained

Optics Letters top downloads “Self-healing of space-time light sheets”

A paper titled “Self-healing of space-time light sheets” by H. Esat Kondakci and Ayman F. Abouraddy is one of Optics Letters top downloads for August 2018. Space-time (ST) wave packets are diffraction-free, dispersion-free pulsed beams whose propagation invariance stems from correlations introduced into their spatio-temporal spectra. We

Nondegenerate Two-Photon Gain in Semiconductors

Lasers operate by stimulated emission, where a single photon is emitted per electronic transition. Two photons, with combined energy matching the transition energy, can also stimulate emission of two additional photons in a process known as two-photon gain (2PG). Just
