HexaTech and Tokuyama Collaborate to Produce Record UV-C LED Performance

(PR Web Via Acquire Media NewsEdge) Morrisville, NC and Tokyo, Japan (PRWEB) October 03, 2012 The rapidly accelerating interest in light emitting diodes (LEDs) for disinfection applications operating at UV-C wavelengths requires a solution with high output power, high efficiency and long lifetimes. HexaTech, Inc. today announced the results of an ongoing collaboration with development partner Tokuyama Corporation of Tokyo, Japan, which has demonstrated exceptional output power and dramatic internal quantum efficiency (IQE) improvements. These results raise the bar to what is possible with the technology, and enable commercially available high performance, high reliability UV-C LEDs.

By coupling HexaTech’s industry-leading low dislocation density bulk aluminum nitride (AlN) substrates, with Tokuyama’s hydride vapor phase epitaxy (HVPE) and device fabrication, Tokuyama was able to produce UV-C LEDs with over 25 mW of output power at 265 nm, and internal quantum efficiencies greater than 70%.

“This collaboration demonstrates that when combining HexaTech’s market-leading bulk substrate quality, with Tokuyama’s high quality HVPE and excellent device fabrication, breakthrough, record-setting results are possible”, noted Joe Grzyb, HexaTech CEO. “It further highlights our commitment to working with our customers to bring the best in aluminum nitride technology to market.” “Working together with HexaTech and their substrates, Tokuyama has made great improvements in the performance of our UV-C LEDs, accelerating the process for their commercial availability “, stated Mr. Toru Kinoshita, Chief Research Engineer at Tokuyama Corporation.

Since their inception, UV-C LEDs have held the promise of a compact, highly efficient, long-life light source for sterilization and purification applications. However, most commercially available products currently struggle with limited output power, efficiency and device lifetimes. A key requirement for improving these limitations is to drive the device defect density down, for which IQE is a key measure and is critically related to the underlying bulk material quality.

“As HexaTech’s own device development has shown, using our high quality, low dislocation material, we are able to produce UV-C LEDs with record-setting reliability and lifetimes, exceeding more than 600 hours of accelerated testing, with virtually no degradation”, commented Dr. Baxter Moody, HexaTech Director of Device Development.

About HexaTech HexaTech is an industry-leading manufacturer of single crystal Aluminum Nitride (AlN) substrates. This substrate material will enable long life UV-C light emitting diodes (LEDs) for disinfection applications, deep UV lasers for biological threat detection, and high voltage power semiconductors for smart grid and efficient power conversion.

HexaTech’s current product lines include single crystal and polycrystalline AlN substrates. Long life UV-C LEDs and high voltage power devices based on AlN substrates are also in development.

Founded in 2001 with a team of industry experts in III-nitride semiconductors, the team has successfully solved complex material science and engineering challenges to commercialize high quality bulk AlN for volume production.

Oracle in Enterprise Communications

Most in the industry have heard of the acquisition of Acme Packet by Oracle. What you may not know is that Oracle has a number of telecommunications products including a UC suite, WebRTC Session Controller, and Operations monitoring tools. Oracle is pursuing both the enterprise and service provider.

WebRTC Security Concerns

This whitepaper covers two of the most relevant topics in communications industry today: WebRTC and security. We will introduce the problem of security in WebRTC including those traditional VoIP attacks that are going to be present in WebRTC services. Later we will mention ad-hoc WebRTC attacks and protection mechanisms, to close with an overview of identity management solutions.

Migrating Real Time Communications Services to the Web

In the Internet age, businesses that own fixed and mobile communication networks, including traditional Communications Service Providers (CSPs) of all kinds, are being challenged with some tough questions: How do we stay relevant to our customers?

Delivering Enterprise-Class Communications with WebRTC

WebRTC is an emerging industry standard for enabling Web browsers with real-time communications capabilities. It enables enterprises to enhance Web sites, empower BYOD users, and improve video collaboration and on-line meetings, to name but a few examples.

Robust Enterprise Grade WebRTC Systems and Services


The emerging WebRTC standard has become one of the industry's hottest topics – and with good reason. Being able to "communications enable the web" has Communications Service Providers as well as Enterprises busily making plans for deployment. But, as these plans unfold, reality is starting to intrude on those plans. Our expectations of telephony services are much higher than web browsing. We expect the phone to connect instantly, operate with minimal disruption, and work seamless across any network, anywhere, at any time. There is also an understanding that phone service is inherently secure. With WebRTC, the expectation is for these applications to behave in the same manner.

This session looks at the user experience and expectations of a WebRTC Enterprise service. It will also cover how a WebRTC enterprise handles security, reliability, and interoperability within browsers and networks.

ORACLE COMMUNICATIONS WEBRTC SESSION CONTROLLER SOLUTION

Communication Service Provider (CSP) voice service revenues continue to face pressure due to shifts in communication preferences and competition from non-traditional service providers. Voice communications are now often embedded into applications outside the domain of traditional telephony voice usage. CSPs have been challenged to effectively leverage and monetize new web-oriented communications technologies.
