March 6, 2007...Acreo, a semiconductor and optical networking company, has spun-off a separate
company, IRnova AB based on Acreo’s experience with quantum well infrared
photodetectors (QWIP). Acreo will own the majority of IRnova; employees will
own the remaining stake. IRnova’s main technology uses aluminum gallium
arsenide (AlGaAs) on a gallium arsenide (GaAs) substrate to produce the quantum
wells.
During 2005-2006 calendar years, IRnova substantially increased its production
capacity in the number of infrared detectors the organization produces per year.
During 2006 Acreo says that IRnova received substantial new orders and customers
which required a need for volume production of QWIP detectors. Acreo says that
IRnova is already a leader in supplying QWIP detectors and solutions for QWIP
focal plane arrays. Factory floor monitoring and medical testing devices are
a couple of the applications of QWIP technology can be used for beyond the military
applications which dominated early development efforts. Acreo

Corporation News Release Panasonic Develops White LED on GaN Substrate for Volume Production
LIGHTimes StaffMarch 6, 2007...Panasonic, the best known brand under Matsushita Electric Industrial Co. Ltd,
reported that it has developed a blue LED element on a gallium nitride (GaN)
substrate. The company plans to begin mass production of the white high-power
LED series in mid March 2007. GaN substrates can boost performance of LEDs because
of GaN’s high thermal and electrical conductivity. GaN substrates have
the same refractive index as the light-emitting layer. Panasonic says using
their high quality, lower priced GaN substrates results in an LED with 1.5
times efficiency in lumens per watt as the conventional sapphire-based LED element.
In conventional sapphire-based LEDs, poor heat dissipation properties tend to
result in saturation of output at high currents. Content continues for LIGHTimes SecondPage members... Anadigics Launches 3G HSPA Transmit Modules

News Release Rensselaer Researchers Create Anti-Reflective Material for More Efficient Solar Cells or LEDs
LIGHTimes StaffMarch 1, 2007...A report, which will appear in the March issue of Nature
Photonics, explains how researchers at Rensselaer Polytechnic Institute
have created a special material that reflects virtually no light. The research
could lead to brighter LEDs, more efficient solar cells, and a new class of
“smart” light sources that adjust to the environment. The material
the researchers created is an order of magnitude less reflective than what was
previously the least reflective material. In fact the researchers say that it
has almost the same refractive index as air. The refractive index is a fundamental
optical property of a material. It governs the amount of light a material reflects,
as well as other optical properties such as diffraction, refraction, and the
speed of light inside the material. The material they created has refractive
index of 1.05. As a comparison, window glass reportedly has a refractive index
of 1.45. Content continues for LIGHTimes SecondPage members... Avanex Divests in French Optoelectronic Fabs

News Release KDDI and Fujitsu Jointly Develop Amplifier of Next Generation Mobile WiMAX
CompoundSemi News StaffMarch 2, 2007...KDDI Corporation, Fujitsu Limited, and Fujitsu Laboratories Ltd. of Japan announced
that they have jointly developed a high-efficiency amplifier for mobile WiMAX
(IEEE 802.16e-2005), a next-generation wireless broadband communications protocol,
according to Japan’s Corporate News Network. The joint development efforts
of Fujitsu and KDDI started in May 2006. KDDI reportedly had been exploring
ways to make base stations smaller and more energy efficient to ultimately reduce
costs required for a mobile WiMAX system infrastructure and operation. Amplifier
performance dictates much of the performance of base station equipment. Fujitsu
notes that high efficiency amplifiers can reduce size, weight, noise, and maintenance
requirements while improving efficiency.
In particular, amplifiers dictate the performance of base station equipment.
High-efficiency amplifiers can enable various benefits for base station equipment
such as downsizing, lighter weight, greater power efficiency, less noise, and
moving closer to becoming maintenance-free. Fujitsu says that the improved efficiency
of the amplifiers will also make it possible to lower cost of support equipment
for base stations base stations such as equipment for power sources and air
conditioning.
Fujitsu said it was able to construct a prototype transmitter amplifier using
a gallium-nitride (GaN) HEMT device that was developed by and later enhanced
by Fujitsu Laboratories. Fujitsu was able to enhanced the prototype performance
by optimizing the design of the amplifier circuits for higher efficiency and
making improvements to its digital pre-distortion technology which has already
been used successfully in 3G systems. The company succeeded in developing a
prototype transmitter amplifier that achieves power efficiency of roughly 30
percent with 25 watt power output at 2.5 gigahertz (2.5GHz) operational frequency
band. Fujitsu contends that the device’s efficiency is double the level
of conventional amplifiers, and the development of the amplifier prototype paves
the way for practical use of GaN HEMT-based high-efficiency amplifiers. Fujitsu

News Release Emcore Seeks to Expand Patent Litigation Against Optium
CompoundSemi News StaffFebruary 28, 2007...Emcore announced that it is seeking to expand its patent litigation against
optoelectronic component maker, Optium. Both JDSU and Emcore filed a patent
lawsuit against Optium on Septermer 11, 2006 in the U.S. District Court for
the Western District of Pennsylvania. The original complaint alleges that Optium’s
Prisma II 1550nm transmitters violate two patents that Emcore licenses from
JDSU, U.S. patent No. 6,282,003
(the ‘003 patent) and 6,490,071
(the ‘071 patent). (Ref: Coverage).
Emcore has added an addition patent that the company licenses from JDSU, U.S.
patent No. 6,519,374
("the '374 patent") and an additional product line to this litigation.
Instead of alleging that Optium’s Prisma II 1550nm transmitters infringe
the patents, Emcore would like to specify that the company’s 1550nm externally
modulated transmitters and its 1550 nm QAM transmitters infringe the patents.
The three patents relate to the transmission of video, voice, and data for the
CATV (cable TV) market.
"Emcore continues to put considerable resources into developing unique
technologies that are key to transmission of video, voice and data, and which
support Emcore's stature in the CATV market," said Dr. Hong Q. Hou,
President and COO of Emcore. "Similarly, we will deploy considerable
resources to ensure that our intellectual property is respected. We believe
that Optium has infringed on several of our licensed patents and we will aggressively
pursue any misuse of our intellectual property by Optium or any other companies
and individuals," he said. Emcore
