The superconducting nanowire single-photon detector (SNSPD or SSPD) is a type of optical and near-infrared single-photon detector based on a current-biased superconducting nanowire. [1] It was first developed by scientists at Moscow State Pedagogical University and at the University of Rochester in 2001.
Nanowire lasers are similar to Fabry–Pérot cavity in mechanism, but different in quantitative reflection coefficients [30] [31] High reflectivity of nanowire and flat end facets of the wire constitute a good resonant cavity, in which photons can be bound between the two ends of the nanowire to limit the light energy to the axial direction of ...
Nanowire lasers can be grown site-selectively on Si/SOI wafers with conventional MBE techniques, allowing for pristine structural quality without defects. Nanowire lasers using the group-III nitride and ZnO materials systems have been demonstrated to emit in the visible and ultraviolet, however infrared at the 1.3–1.55 μm is important for telecommunication bands.

EMVA1288 compliant logo. EMVA1288 [1] is an electronic measurement standard developed by the European Machine Vision Association (EMVA). Its purpose is to define the methods to measure and characterize image sensors and cameras that are used in machine vision.
Schematic of silicon nanowire. Silicon nanowires, also referred to as SiNWs, are a type of semiconductor nanowire most often formed from a silicon precursor by etching of a solid or through catalyzed growth from a vapor or liquid phase. Such nanowires have promising applications in lithium-ion batteries, thermoelectrics and sensors.
Niobium nanowires in form oxide or nitride are used to detect single photons at low temperatures. The superconducting nanowire single-photon detector is an example of something made from these nano-structured materials. [1]
As a nanowire shrinks in size, the surface atoms become more numerous compared to the atoms within the nanowire, and edge effects become more important. [citation needed] The conductance in a nanowire is described as the sum of the transport by separate channels, each having a different electronic wavefunction normal to the wire. The thinner ...
Developments in analysis, device miniaturization, fluidic design and integration have catapulted the development of integrated photonic crystal sensors in what is known as lab-on-a-chip devices of high sensitivity, low limit of detection, faster response time and low cost. [3]
