Mitsubishi Chemical to produce high-power laser diodes used in Blu-ray pick-up heads




Japan-based Mitsubishi Chemical, in view of global short supply of Blu-ray Disc (BD) pick-up heads (PUHs), is planning to step into production of high-power (200-300mW) laser diodes (LDs), the key component of PUHs for BD burners, according to sources in the Taiwan optical disc drive (ODD) industry.
