A development based on the nitride green project of the laser diode (PolarCoN engineering) funding of 2 million euros. Eight team from Germany and Switzerland to form a joint team, to develop the nitrogen base green laser diode. The project was named PolarCoN engineering, has been from the German research foundation and the Swiss national science foundation to obtain the first batch of 2 million euros in funding, the project's first phase will run until 2011. "This project has several important stage", from the university of Ulm in Germany project coordinator Ferdinand Scholz said. These stages including 3 years later to develop light pump without/half polarity green laser diode (500 nm wavelength >), another 3 years to develop low threshold electric pump pu no/half polarity blue laser diode. Although the first phase will be completed by the university team, scholz said, osram opto semiconductors company also had certain inputs. "The idea is in the second phase of engineering for the participation of the industry", he said, "if the first cycle of between 2008 and 2011 for success, in the next three years, we expect to get more money. PolarCoN's goal is to eliminate the" green light cracks ", at present, compared to the conventional blu-ray and ultraviolet diode based on GaN green light diode efficiency is low. The current one obstacle is GaN polarity characteristics and related compounds, especially along the crystal device c - axis direction growth. PolarCoN researcher seeks to control the nitrogen group III base heterostructure polarization effect, find out the ways to the future can be accepted by photoelectric device industry. "because there are a lot of external organizations to participate in, different methods will be tried, focus mainly on the structure and material of the green laser diode optimization", semi - polar said.
