Semiconductor–superconductor optoelectronic devices

Abstract

Devices combining superconductors with semiconductors offer a wide range of applications, particularly in the growing field of quantum information processing. This is due to their ability to take advantage of both the extensive knowledge gathered in the field of semiconductors and the unique quantum properties of superconductors. This results in novel device concepts, such as structures generating and detecting entangled photon pairs as well as novel optical gain and laser realizations. In this review, we discuss the fundamental concepts and the underlying physical phenomena of superconductor–semiconductor optoelectronics as well as practical device implementations.

Harnessing ultraconfined graphene plasmons to probe the electrodynamics of superconductors

“…Hence, electromagnetic near fields provided by, for instance, plasmons, emitters, or small scatterers can couple to such amplitude fluctuations and therefore constitute a feasible, promising avenue toward experimental observations of the Higgs mode in superconductors. In this context, ultraconfined graphene plasmons ( 22 , 23 ) constitute an additional paradigm for probing quantum nonlocal phenomena in nearby metals ( 23 – 28 ), while their potential as tools for studying the intriguing electrodynamics of strongly correlated matter ( 29 – 31 ) remains largely virgin territory.…”

High-T c Cooper-pair injection in a semiconductor–superconductor structure

“…(Some figures may appear in colour only in the online journal) Hybrid superconductor-semiconductor structures form a rapidly growing field of research [1,2], which utilizes the unique physical properties of the superconducting state [3] along with the vast knowledge and fabrication capabilities in the field of semiconductors. Various applications involving such hybrid structures have been shown, including superconducting light-emitting diodes (SLEDs) and quantum dots [4][5][6], Bell-state analyzers [7] and superconductor-based waveguide amplifiers [8].…”
