Abstract

The optical packaging of receiver arrays presents two difficult problems, one common to other arrays, and one peculiar to those involving detectors. Coupling light between arrays is typically more challenging than coupling to individual components, because both angle and position must be controlled precisely. Coupling to an array of detectors presents the additional problem of changing the beam direction. Unlike most lasers or waveguide components, many detectors "look up" out of their substrate plane. Linear arrays containing only detectors can be mounted at right angles to a substrate, so that fibers can be kept in the plane of the substrate, but this is not practical for receiver arrays, which are much larger.
