Nichia set to sample 400-nm laser diode eetimes.com By Yoshiko Hara EE Times (01/12/99, 3:15 p.m. EDT) ANAN, Japan — A short wavelength laser that could essentially double or triple the capacity of an optical disk will be available for sampling from Nichia Chemical Industries Ltd. in February. Nichia, a leading supplier of InGaN-based blue-violet laser diodes, next month will sample a 400-nanometer violet semiconductor laser with a lifetime of about 10,000 hours and a constant output power of 5 milliwatts. Production is expected to begin soon after sampling commences. Nichia has already presented papers on laser diodes with lifetimes of 10,000 hours when operating at 2 mW output power. For commercialization, Nichia has improved the structure between the sapphire substrate and the laser diode structure. The DVD Forum said a short wavelength laser in the blue or shorter range is the key component for a third-generation DVD-RAM disk with a capacity above 15 Gbytes.
