Abstract
Provided are an optical receiver and a method of forming the same. The optical receiver includes a lens, a photo detector, and a hetero-junction bipolar transistor. The lens is attached to a backside of a substrate. The photo detector is disposed on a top surface of the substrate. The hetero-junction bipolar transistor is disposed on the top surface of the substrate. The lens condenses an incident optical signal to transmit the condensed optical signal to the photo detector.
