Abstract
A constructed photodetector, an optical receiver, and a receiver unit in an optical communication system are disclosed. One example of the disclosed constructed photodetector includes an optoelectronic element having an active area that converts light having a wavelength of interest into electrical signals and a substrate on a face that opposes the active area, where the substrate is non-transparent to light having the wavelength of interest. The constructed photodetector further includes a lens-chip that is at least partially transparent to light having the wavelength of interest, where the lens-chip includes a first side and an opposing second side, where the first side of the lens-chip includes an integrated lens, and where the second side of the lens-chip includes one or more electrical traces. The constructed photodetector further includes at least one connector that provides a physical and electrical connection between the optoelectronic element and the lens-chip.
