Aspects of the subject disclosure may include, for example, receiving an optical signal; splitting the optical signal into multiple paths including a direct path, a first delay path, and a second delay path, where the splitting includes directing a first portion of the optical signal through the direct path to a photodetector, where the splitting includes selectively directing a second portion of the optical signal through the first and second delay paths of different lengths to introduce selectable and variable optical delays; directing the second portion of the optical signal from the first and second delay paths to the photodetector; and generating a photocurrent from the first portion and second portion of the optical signal at the photodetector. Other embodiments are disclosed.
