Blue lasers continue to set the pace in optoelectronics

AbstractRecent indicators as to the status the III-nitrides and related compound semiconductors — not the least being our own GaN market report — reaffirm the signs of continuing innovation and development in new devices and thus new markets. To this must be added the evolution of existing ones such as the blue LED. However, the blue laser diode constitutes the leading edge of advanced optoelectronics research and no better is this exemplified than by Nichia labs. Collectively, this R&D thrust is serving to bring closer the second renaissance in a very important sector of our industry
