Abstract:
1. A dynamically configurable multiple wavelength adapted photodetector (PD) integrated circuit, comprising: a PD array comprising a center bank of electrically isolated PD sections, and a first and a second side channel bank of electrically isolated PD sections on opposing sides of said center PD bank, said sections for receiving light and outputting electrical signals; a dynamically configurable switching matrix having a first plurality of inputs coupled to outputs of said PD sections and a second plurality of inputs for receiving control signals which select from a plurality of different switch configurations, wherein said switch configurations set which of said PD sections are coupled to particular ones of a plurality of matrix outputs provided by said switching matrix; structure adapted to provide switching matrix configuration information coupled to the second plurality of inputs of the switching matrix to thereby select specific ones of the plurality of different switch configurations; and an output stage comprising a plurality of output amplifiers coupled to said plurality of switching matrix outputs and adapted to provide a plurality of amplified outputs, wherein dynamically adjustable combinations of electrical signals from said PD sections are provided to said plurality of amplifiers based on said switching matrix configuration for adjusting a centering of incident side beams relative to said side channel PD banks.
