of determining the status of the remainder of the finished goods as well as the status of the Company’s raw materials.


While Fabrinet maintains insurance for the equipment and inventory located at the facility (and Opnext maintains independent insurance for a portion of the inventory) and there are additional contractual protections in favour of Opnext that Fabrinet has stated it will honour, it is not clear that the insurance will be adequate to fully cover Opnext’s losses or that Opnext will otherwise be made whole.


Infinera top dog in North America


In Q3 2011, the indium phosphide PIC provider achieved number three position worldwide in the terrestrial long haul WDM transport and ROADM market


Infinera, provider of InP based digital optical networking solutions, has announced that Infonetics Research ranks Infinera the number- one supplier in the North America terrestrial long-haul WDM transport and ROADM market. This ranking demonstrates the company›s continual growth and market reach.


«In the third quarter of 2011, Infinera posted a revenue increase that moves them into first position in North America and third position worldwide for combined terrestrial long-haul WDM transport and ROADM equipment,» noted Andrew Schmitt, directing analyst for optical at Infonetics Research.


Infinera›s market share results in the third quarter for North America were driven largely by leading cable companies, wholesale carriers, Tier 1 customers and Internet Content Providers. European wholesale carriers and opportunities in the submarine space contributed to the company›s third quarter growth worldwide.

«Global network operators benefit from the scale, simplicity and efficiency of Infinera›s optical network solution,» said Tom Fallon, Infinera CEO. «Infinera›s solution for network operators helps them be more responsive to their customers› needs while confidently planning for future network growth. We are pleased by Infonetics› ranking as this reflects the support and faith our customers continue to put in us.»


Infinera›s product portfolio includes Infinera›s DTN platform, powered by photonic integrated circuits (PICs), Infinera ATN, a scalable metro WDM transport platform and the recently announced DTN-X platform with 500 Gb/s FlexCoherent super-channels.


InAs/InGaAs QDs for ultra- high speed communication


Using a sandwiched sub-nano separator growth technique, indium arsenide / indium gallium arsenide quantum dots have been used to create a broad new band the 1.31-μm region


The National Institute of Information and Communications Technology (NICT) says it has developed the world’s first optical source for generating light spanning a large number of wavelengths with high precision.


The researchers used nanoscale InAs/ InGaAs quantum dots grown on GaAs, in a band consisting of wavelengths in the 1.3-μm region that are not currently used for optical communication.


What’s more, the researchers say they have developed an optical transmission experiment using this light source and a photonic crystal fibre, demonstrating the possibility of using a new wavelength band for optical communication.


This “quantum dot light source technology” makes it possible to secure an optical
