Development Points to Potential for 100-Fold Improvement in Nanopillar LED Efficiency
Researchers from Eindhoven University of Technology have created a very efficient nanopillar LED. The team fabricated the nanopillar LED with a metal cavity in a III-V layer stack attached to a silicon substrate. The device achieved “relatively high” on-chip external quantum efficiency (10−4 to 10−2 for room-temperature and 9.5 K, …
Researchers Test “DarkLight” Communication
Researchers at Dartmouth have developed communication prototype that uses LEDs to transmit data. Unlike conventional Visual Light Communication, however, the LEDs emit light in pulses so quickly that that are invisible to the human eye. Hence, the researchers have dubbed the technology, “Dark Light” communication. They used off the shelf …
LESA Develops High-Speed VLC Link with Integrated Microchip Receiver
The Center for Lighting Enabled Systems and Applications (LESA), an Engineering Research Center headquartered at Rensselaer Polytechnic Institute (RPI), recently claimed to have achieved the world’s first high-speed visible‐light transmission link with a fully integrated microchip receiver. According to the LESA ERC, the low‐cost, compact, integrated microchip receiver that its …
VLC Market Poised to Explode
The visible light communication market is poised to explode, according to Global Market Insights. In 2014, the visible light communication (VLC) market size was valued about USD 300 million. Global Market Insights (GMI) projects that the VLC market will grow at a CAGR of over 90% over the forecast period …
Nanocrystal Perovskite Material Shows Potential for Laser-based VLC Tranmission of Up to 2 Gbps
Researchers at King Abdullah University of Science and Technology (Kaust) have developed a light emitting material using perovskite nanostructures that can be turned on and off through lasing faster than LEDs can turn on and off. This capability can lead to visible light communication with data rates of up to …
pureLiFi Gets Additional Funding; Hopes to Unlock Potential of IoT
pureLiFi, a company, founded, by professor Harald Haas of the University of Edinburgh, reports that it has completed its Series B Financing Round. Temasek, a Singapore-based investment firm led the round of financing. Total funding raised for the company is $10 million so far. Dr. Haas and his company pureLiFi …
Disney Research and Eth Zurich Create VLC System Starting With Off-the-Shelf LED Bulbs
Disney Research and Eth Zurich have shown that consumer grade LED bulbs, with some modifications, can both illuminate and serve as a communication link for devices within the room. Stefan Schmid, a Ph.D. student at Disney Research and ETH Zurich pointed out that such a visible light communication system could connect …
Visible Light Communication Market to Increase Exponentially
The global Visible Light Communication (VLC)/Light Fidelity/(Li-Fi) market was valued at USD 454.8 million in 2015, according to Grand View Research Inc. The company forecasts that rising adoption of communication technology and exponential increase in the number of internet users will drive the VLC market between 2015 and 2024. Grand …
