across the entire available wavelength range that is used.
Within the wavelength range of 910 nm to 1070 nm, Oclaro offers seven standard wavelength windows with up to 200 W on a microchannel cooler and up to 120 W on the industry’s standard passive mini-cooler, the Oclaro BLM.
This Oclaro family of mounted bar products enables the scaling of system power up to 15 kW. With on-going innovation efforts, Oclaro recently demonstrated output powers of up to 350 W on a microchannel cooler and 250 W on a passive mini-cooler which illustrates the technology reach.
“Today’s announcement underscores our ability to deliver a comprehensive portfolio of solutions for direct diode applications and highlights the extensive technology and design capabilities we have assembled in-house to achieve industry-leading performance,” says Gunnar Stolze, VP of Sales for the Global Industrial and Consumer business at Oclaro, Inc.
“By offering the industry’s broadest wavelength range while consistently delivering product performance and reliability, our customers have the flexibility to scale system power as needed to better respond to their customer’s needs,” adds Stolze.
Imra on the war path with Coherent
The firm is alleging that Coherent has infringed patents essential for the precise micromachining of most materials used for microelectronics application lasers
Imra America, Inc., has filed a patent infringement lawsuit at the District Court of Duesseldorf in Germany.
The allegation has been made against the German subsidiaries of Coherent Inc., namely Coherent Kaiserslautern GmbH (formerly Lumera Laser GmbH) and Coherent (Deutschland) GmbH.
The lawsuit asserts that certain laser products marketed by Coherent in Germany infringe the German part of the European Patent 0 754 103 B1 “Method for controlling configuration of laser-induced breakdown and ablation”.
The suit involves a patent considered essential for the precise micromachining of most materials used for microelectronics applications with picosecond and femtosecond lasers. Material examples given in the patent are gold and glass.
The European Patent 0 754 103 B1 was invented by Professor Gerard Mourou (Presently Professor of the Ecole Polytechnique Haut Collège) and his colleagues while he was at the University of Michigan. Imra is the exclusive licensee of this patent for all non biological applications.
“We have multiple license agreements with many laser manufacturers,” Takashi Omitsu, President of Imra America remarks, “We truly try to avoid filing lawsuits. However, we could not come to a reasonable solution with them for both our existing licensees and ourselves. We filed this suit as a last resort.”
Imra’s technology portfolio includes over 450 US and international patents and patent applications. The company’s pioneering technologies, rigorous quality control and high volume manufacturing operation make its products for scientific, OEM and industrial use. Imra also to research areas in new functional nano-materials for bio-medical and energy applications.
SEMI highlights the need for InP and GaAs
The organisation says that the restriction of the use of indium phosphide and gallium arsenide would have a negative impact on the semiconductor industry and Europe as a whole. SEMI has also described a new directive which will bring down patent application costs
According to Heinz Kundert, president of SEMI Europe, being able to quickly identify and seize the potential offered by new technologies and new markets is critical in the semiconductor industry. Keeping track of public policy developments is equally important.
Decisions made in a national Ministry or an EU institution can have a direct impact on the industry.
A new EU patent procedure, to be introduced by mid- 2014, will significantly reduce the cost and time for a company to obtain a patent valid across 25 European states. The outcomes of the current review of substances under European EHS rules, for example, may have an impact on industry’s research priorities or its access to the EU market.
This article covers these topics: 7th SEMI Brussels Forum; EU Patent Protection; GaAs and InP under Review (REACH); RoHS Exemptions Expiring; Banned Substances under RoHS; EU Conflict Minerals Debate.
The SEMI Brussels Forum is one of Europe’s leading policy events for semiconductor equipment and
