A dynamically configurable multiple wavelength adapted photodetector (PD) integrated circuit includes a PD array having 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 the center PD bank for receiving light and outputting electrical signals. A dynamically configurable switching matrix having a first plurality of inputs is coupled to outputs of the PD sections and a second plurality of inputs is provided for receiving control signals which select from a plurality of different switch configurations. The switch configurations set which of the PD sections are coupled to particular ones of a plurality of matrix outputs provided by the switching matrix. A structure providing switching matrix configuration information is coupled to the second plurality of inputs of the switching matrix to selects specific ones from the plurality of different switch configurations. An output block comprising a plurality of amplifiers is coupled to the plurality of matrix outputs for providing a plurality of amplified outputs, wherein dynamically adjustable combinations of electrical signals from the PD sections are directed to the plurality of amplifiers based on the switch configuration. The configuration selected effectively centers a location of an incident side beam at a center of the side channel PD banks independent of a wavelength (and resulting position) of the beam.
