Many years of effort were needed to develop blue light-emitting diodes and lasers, but devices based on indium gallium nitride are now set to revolutionize optoelectronics. The first blue laser, unveiled in 1995, caused much excitement in the optoelectronics industry. Shuji Nakamura describes the advances that enabled his group to end over 30 years of research and development
