The research team that announced the first optical rectenna in 2015 is now reporting a two-fold efficiency improvement in the devices — and a switch to air-stable diode materials. The improvements cou...
Physicists at the University of California, Riverside have developed a photodetector – a device that senses light – by combining two distinct inorganic materials and producing quantum mechanical proce...
Adapting to a time-varying channel to maximize the average information rate for a given power constraint is a well-understood problem. Important studies (e.g., [I], [Z], [3]) have developed optimal ra...
We transmit 106x200 Gb/s channels over 10,290 km at 6.0 b/s/Hz enabled by Nyquist spectral shaping and nonlinearity compensation. We also transmit 53x400 Gb/s channels over 9,200 km detecting two 200 ...
We transmit 32 WDM channels over 12 spatial and polarization modes of 177 km few-mode fiber at a record spectral efficiency of 32 bit/s/Hz. The transmitted signals are strongly coupled and recovered u...
Terrestrial Laser Scanning is a popular and widely used technique to scan existing objects, document historical sites and items, and remodel them if and when needed. Their ability to collect thousands...
The role of the carrier’s recombination velocity Si within the depletion Layer of p-n junction solar cell and the external bias voltage Va across the junction in determining the current density “J” th...
SiO2Al2O3 double dielectric stack layer was deposited on the surface of the GaN-based light-emitting diode (LED). The double dielectric stack layer enhances both the electrical characteristics and the...
A novel transflective liquid crystal display (LCD) with a microtube array structure to make the most effective use of backlight was demonstrated. By redefining the area ratio of transmissive and refle...
An autostereoscopic display with parallax barrier attached onto a liquid crystal panel suffers from the trade-off between brightness and crosstalk. One approach for making improvement by modifying the...
We present a new optical system with two identical s- and p-polarized light paths for converting a random polarized beam into a linearly polarized one. The system also provides a uniform and rectangul...
High-efficiency color filters composed of a microprism array, optical interference color filters, and a microlens array light compressor were developed to increase the optical throughput of liquid-cry...
A novel transflective liquid crystal display (LCD) with a microtube array structure to make the most effective use of backlight was demonstrated. By redefining the area ratio of transmissive and refle...
A pyramidal array light-enhancing layer (pyramidal ALEL) on an organic light emitting diode (OLED) panel has been optimized to enhance the luminance efficiency with a gain factor of 2.03 experimentall...
This paper illustrates the results of a research focused on the development of a multi-scale geodatabase designed to store the data needed to measure the energy buildings performance of buildings to b...
