Abstract
Abstract A photodetector assembly includes a slice of semiconductive material having a photodetector array formed thereon. The slice is supported on a substrate. A fiber optics bundle is closely spaced and coupled optically to the devices of the array. In one embodiment, the substrate is apertured. Contacts space the slice from the substrate with the array positioned over the aperture. The bundle extends into the aperture, terminating at the surface of the substrate. In another embodiment the slice is bonded to a depression in the substrate with the array facing away from the substrate. An apertured cap is mounted over the substrate, with the bundle extending into the aperture.
