This article describes the basic principles of semiconductor quantum-dot infrared photodetectors based on conduction-band intersublevel transitions. Sufficient background material is discussed to enable an appreciation of the subtle differences between quantum-well and quantum-dot devices. The article first considers infrared photon absorption and photon detection, along with some metrics for photon detectors and the detection of infrared radiation by semiconductors. It then examines the optical matrix element for interband, intersubband and intersublevel transitions before turning to experimental single-pixel quantum-dot infrared photodetectors. In particular, it explains the epitaxial synthesis of quantum dots and looks at mid-wave and long-wave quantum-dot infrared photodetectors. It also evaluates the characteristics of quantum-dot detectors and possible development of quantum-dot focal plane array imagers. The article concludes with an assessment of the challenges and prospects for high-performance detectors and arrays.

AbstractConverting incoming photons to electrical current is the key operation principle of optical photodetectors and it enables a host of emerging quantum information technologies. The leading approach for continuous and efficient detection in the optical domain builds on semiconductor photodiodes. However, there is a paucity of efficient and continuous photon detectors in the microwave regime, because photon energies are four to five orders of magnitude lower therein and conventional photodiodes do not have that sensitivity. Here we tackle this gap and demonstrate how microwave photons can be efficiently and continuously converted to electrical current in a high-quality, semiconducting nanowire double quantum dot resonantly coupled to a cavity. In particular, in our photodiode device, an absorbed photon gives rise to a single electron tunneling through the double dot, with a conversion efficiency reaching 6%.
