A new single chip optical CMOS detector for next generation optical storage systems

In this paper a new fully integrated detector architecture for pick-up units in optical storage systems is presented. Apart from a special diode constellation for data recovery it features a 5x5 diode matrix for determination of the average spatial light power distribution across the detector. The chip, fabricated in a standard 0.6µm CMOS process, operates at a 3.3V power supply and occupies 1.78x1.58mm2. It includes six high frequency readout and one low frequency readout paths.
