Infrared (IR) Spectroscopy: Overview

Infrared (IR) Spectroscopy: Overview

When electromagnetic radiation passes through a material, atoms or molecules transition from a lower to a higher energy state by absorbing radiation corresponding to the energy difference between the two states. The absorption of infrared (IR) radiation causes transitions between vibrational energy levels in a molecule. Therefore, IR spectroscopy is a useful analytical tool for determining the molecular structure of molecules.
Different compounds display unique properties due to their...

Background:

Mid-infrared (MIR) single-photon detection is crucial for applications like communications, sensing, astronomy, and biomedicine.
Direct time-correlated single photon-counting in the MIR has been a significant technological hurdle.

Purpose of the Study:

To demonstrate a single-pixel scanning light detection and ranging (LiDAR) system operating in the MIR at the single-photon level.
To achieve sub-millimeter depth resolution for MIR LiDAR using advanced superconducting nanowire single-photon detectors (SNSPDs).

Main Methods:

Utilized a differential impedance-matched tungsten silicide (WSi) superconducting nanowire single-photon detector (SNSPD) optimized for MIR wavelengths.
Employed an optical parametric oscillator (OPO) laser source operating at 3500 nm.
Implemented a single-pixel scanning LiDAR configuration for depth profiling.

Main Results:

Achieved sub-millimeter depth resolution in the single-photon regime at 3500 nm.
Demonstrated the detector's capability to resolve fine features at a distance of 100 mm.
Characterized the wavelength-dependent photoresponse and timing jitter from 1550 nm to 5438 nm.

Conclusions:

The developed MIR LiDAR system exhibits broadband operation, high timing performance, and single-photon sensitivity.
This work highlights the potential of MIR time-correlated single photon-counting enabled by SNSPDs for advanced applications.
