Furukawa Electric Debuts Semiconductor Lasers for Information and Industrial Electronic Apparatus.TOKYO -- Furukawa Electric (OTC OTC See: Over-the-counter. OTC See over-the-counter market (OTC). :FUWAF), leading provider of semiconductor lasers for long-distance telecommunication, today announced its plan to release 850nm Vertical Cavity Surface Emitting Laser (VCSEL (Vertical Cavity Surface Emitting Laser) Pronounced "vixel." A type of laser diode that emits light from its surface rather than its edge. A VCSEL's circular beam is easy to couple with a fiber, and due to its surface-emission architecture, can be tested ) for information and industrial electronic apparatus. Its lineup is composed of a bare chip An integrated circuit (IC) that has been cut out from the wafer and is ready for packaging. See die. , an arrayed chip, a Chip On Submount (COS) and a Transmitter Optical Sub Assembly (TOSA Tosa Historic region of the Japanese island of Shikoku. It dates at least to the Heian period, when Ki no Tsurayuki (868?–945?), editor of Japan's first imperially commissioned poetry anthology, wrote a fictional diary drawing on his experiences as governor of Tosa. ) and would satisfy a variety of customers' demands. The price points meet requirements to proliferate high speed optical components in a variety of applications such as data-communication, interconnections, encoders, automobile applications, and digital information apparatus. Background Not only the Internet but also a communication between digital information apparatus in office and home has become to require higher speed optical components. And industrial electronic apparatus is using optical sensors in a variety of fields, especially in a factory. The 850nm VCSEL has become popular in the fields because of its high performance and low pricing. Furukawa Electric is a market leader of 1480nm and 980nm semiconductor pumping laser diode A semiconductor-based laser used to generate analog signals or digital pulses for transmission through optical fibers. Both laser diodes and LEDs (light-emitting diodes) are used for this purpose, but the laser diode generates a smaller beam that is easier to couple with the smaller core and 1300nm, 1550nm, CWDM (Course WDM) An optical transmission method that is used for shorter distances than dense WDM (DWDM). Also known as "wide WDM," CWDM transmits fewer channels and uses wider spacing between the channels for distances up to 60 km. Wider spacing up to 25 nm, compared to 1. , DWDM (Dense WDM) The term given to wavelength division multiplexing (WDM) when significantly more channels were being added. Since WDM is increasingly more "dense" all the time, both terms are used synonymously. See WDM. DWDM - wavelength division multiplexing signal laser diodes for the telecommunication. Those technologies and know-how are successfully deployed in this new product. Furukawa has already started sample shipments and will start its volume production this October. Features of This Product The newly released VCSEL, which is made from GaAs material and hires an oxide current confinement, would cover modulation speed up to 10Gbps. The VCSEL also features low power consumption, a wide temperature range from -40 to 125C, and a high reliability. The TOSA, which contains monitor PD and is capable of having either LC connector or SC connector, would also cover 4.25Gbps, the highest speed required for the Fiber Channel application.
