Semiconductor Photon Detectors

Semiconductor optical single-photon detectors

Avalanche Photodiodes (APDs) connected with quenching circuits can be used for single photon detection. This semiconductor photon detector has a better performance than photomultiplier. The principles and applications of APDs are presented. Features, performance of different commercial devices are introduced and compared. Recent research progress based on the improvement of quenching circuits a...

Photon Echoes in Disordered Semiconductor Quantum Wells

Photon echoes occur when a set of inhomoge-neously broadened transitions are rephased after exci-tation by a series of optical pulses. They are the optical analog to spin echoes developed in nuclear magnetic resonance spectroscopy [1]. The primary uses of pho-ton echoes are in coherent transient signal processing and spectroscopy. Due to the rephasing, photon echo spectroscopy can determine the...

Semiconductor scintillator based on photon recycling

Direct-bandgap semiconductor with high quantum radiative efficiency can operate as a scintillator despite being ‘‘opaque’’ to its own luminescence. An interband absorption does not finish off the luminescence but merely creates a new minority carrier, which in turn recombines in a predominately radiative fashion. To take full advantage of this ‘‘photon recycling’’ effect, optically-tight integr...

Photon-assisted transport in semiconductor nanostructures

In this review we focus on electronic transport through semiconductor nanostructures which are driven by ac fields. Along the review we describe the available experimental information on different nanostructures, like resonant tunneling diodes, superlattices or quantum dots, together with the theoretical tools needed to describe the observed features. These theoretical tools such as, for instan...
