In January 2006, Nichia launched a lawsuit against rival LED manufacturer Seoul Semiconductor Co., Ltd., alleging design patent infringement. [10] Nichia and Seoul Semiconductor announced that they have settled all litigation on patent and other issues as well as other legal disputes currently pending between them in the United States, Germany, Japan, United Kingdom, and Korea.
This is a list of semiconductor fabrication plants, factories where integrated circuits (ICs), also known as microchips, are manufactured.They are either operated by Integrated Device Manufacturers (IDMs) that design and manufacture ICs in-house and may also manufacture designs from design-only (fabless firms), or by pure play foundries that manufacture designs from fabless companies and do ...
The laser diode chip removed and placed on the eye of a needle for scale A laser diode with the case cut away. The laser diode chip is the small black chip at the front; a photodiode at the back is used to control output power. SEM (scanning electron microscope) image of a commercial laser diode with its case and window cut away. The anode ...

Osram Opto Semiconductors GmbH of Regensburg, Germany, was a wholly owned subsidiary of Osram GmbH, which was the world's second largest manufacturer of optoelectronic semiconductors [1] after Nichia [2] and followed in third place by Cree Inc. [3] The company was founded in 1999 as a joint venture between Osram and Infineon Technologies.
IPG Photonics Corporation is a manufacturer of fiber lasers. [2] IPG Photonics developed and commercialized optical fiber lasers, [3] which are used in a variety of applications including materials processing, medical applications and telecommunications. [2]
Optical isolator for laser experiments. An optical isolator, or optical diode, is an optical component which allows the transmission of light in only one direction.It is typically used to prevent unwanted feedback into an optical oscillator, such as a laser cavity.
Conventional semiconductor laser diodes generate light by a single photon being emitted when a high energy electron in the conduction band recombines with a hole in the valence band. The energy of the photon and hence the emission wavelength of laser diodes is therefore determined by the band gap of the material system used.
