1.4 - Technologies for Fast Blue and IR PIN Diodes

&
Photo detector integrated circuits (PDIC) for Bluray data storage require high sensitivity and high bandwidth photo diodes. Carriers are generated close to the surface because the used wavelength of 405nm is very short. Standard photo diodes have a low sensitivity for blue light. The latest generation of Blu-ray data storage devices supports 6x to 8x speeds. Next-generation devices will need 12x speed, which requires diode bandwidth of >800MHz, and support for legacy CD and DVD...
