July 31, 2002 — Kopin Corp., a Taunton, Mass., supplier of semiconductor products for voice, video and data products, announced it has produced blue light-emitting diodes (LEDs) that are brighter than conventional LEDs, yet require less power, using a process that creates “nanopockets,” according to a news release. The blue LEDs can be combined with a yellow phosphor to create a white LED.
Nanopockets are structures that confine the production of light away from defects in the LED. Company President John C.C. Fan said solid-state sources for general lighting are the ultimate goal. The results were published in the July 29 edition of the journal Applied Physics Letters.
