US based BinOptics, manufacturer of InP-based etched-facet lasers, is prepared to provide GaN-based 405nm lasers for read-only applications in high denfinition (HD) DVD players. Further, BinOptics claims that its etched-facet technology should cut the cost of 405 nm lasers for HD DVD applications due to higher yields and reduced testing and packaging costs.

BinOptics HCSEL chip technology integrates a horizontal laser cavity with a 45° etched reflecting mirror to direct the beam vertically. According to Morrow, for 405 nm applications the HCSEL technology enables compact integrated device design, and reduces optical head packaging costs. |
You can read more in this article over at Compound Semiconductor.net. They also point to a related story concerning the company's proprietary etched-facet technology (EFT) platform that you may find interesting. EFT uses etching, rather than cleaving, to manufacture the laser facets. The article states that this cleaving operation is costly and can be low-yield step for conventional edge-emitting lasers.
