This paper presents a special photodiode array layout to be used in optical pickup units in combination with optical storage systems. Apart from the features that a standard array offers, this design enables higher resolution of the data recovery diodes. Furthermore, additional diodes for the determination of the spatial light intensity are included. The special layout of the array ensures crosstalk isolation and linearizes the spectral response of the data recovery diodes, enabling lower circuitry requirements for the readout of the photocurrent. The structure was fabricated in standard 0.6 mu m twin well CMOS technology.
