The Opto-Electronics & Systems Laboratories (OES) of Taiwan's Industrial Technology Research Institute (ITRI) has developed GaN blue laser diodes for use in next-generation digital-image optical HD DVD players. According to Pi-Chen Hsu, OES public relations manager, three local companies have indicated interest in a technology transfer for the product.

The new GaN blue laser diodes feature a wavelength of 410nm, enabling a data storage capacity of 15Gb to 20Gb for DVD. It is also suitable for surface-mount packaging, said Hsu. "OES also plans to cooperate with local packaging houses for the packaging," Hsu added.
