Abstract

Quantum Fourier-Transform Infrared Spectroscopy (QFTIR) enables high-resolution, accurate spectroscopy. When combined with quantum imaging, it allows for hyperspectral imaging using undetected photons, accessing the spatial and spectral features of a sample.

Scanless quantum Fourier-transform mid-infrared spectroscopy for solids and surface analysis

Paul Gattinger, Michela Conti, Franziska Dietz +4 more

Quantum infrared (IR) spectroscopy is a novel technique based on nonlinear interferometry and quantum sensing with undetected photons. In this approach, spectrally far-separated correlated photon pairs are used for detection and probing, respectively. Hence, the probing wavelength domain (mid-IR) is substantially different from the detection spectral range (near-IR), which enables shot-noise-limited and cost-effective sensing schemes attractive for applied metrology. In this paper, we implement and employ a custom-built scanless quantum Fourier-transform mid-IR (sQFTIR) microspectrometer for chemical characterization and analysis of solids and interfaces. The sQFTIR system employs spectral-domain acquisition, without the need to scan the optical delay. This results in enhanced sensitivity and short measurement times and therefore enables rapid spectral acquisitions in 100~ms spanning a spectral band from 3000 cm$^{-1}$ - 2400 cm$^{-1}$. The capabilities of our approach are demonstrated for hyperspectral mid-IR imaging of dried pharmaceuticals (insulin on a gold surface) and investigation of a security feature on a banknote. Furthermore, we demonstrate hyperspectral imaging and spectroscopy through a turbid ceramic medium.

Quantum Fourier Transform Infrared Spectroscopy: Evaluation, Benchmarking, and Prospects

Paul Gattinger, Andreas Wolfgang Schell, Sven Ramelow +2 more

Sensing with undetected photons has enabled new, unconventional approaches to Fourier transform infrared spectroscopy (FT-IR). Leveraging properties of non-degenerate entangled photon pairs, mid-infrared (mid-IR) information can be accessed in the near-infrared (near-IR) spectral domain to perform mid-IR spectroscopy with silicon-based detection schemes. Here, we address practical aspects of vibrational spectroscopy with undetected photons using a quantum FT-IR (QFT-IR) implementation. The system operates in the spectral range from around 3000 cm −1 to 2380 cm −1 (detection at around 12 500 cm −1 ) and possesses only 68 pW of mid-IR probing power for spectroscopic measurements with a power-dependence of the signal-to-noise ratio of 1.5 × 10 5 mW −1/2 . We evaluate the system’s short- and long-term stability and experimentally compare it to a commercial FT-IR instrument using Allan–Werle plots to benchmark our QFT-IR implementation’s overall performance and stability. In addition, comparative qualitative spectroscopic measurements of polymer thin films are performed using the QFT-IR spectrometer and a commercial FT-IR with identical resolution and integration times. Our results show under which conditions QFT-IR can practically be competitive or potentially outperform conventional FT-IR technology.

Applied Hyperspectral Mid-IR Quantum Imaging

Sensing with undetected photons has become a distinct research field with numerous demonstrated applications especially dedicated to mid-infrared wavelength regions. These spectral bands allow one to probe sample compositions spectroscopically - bypassing the need for invasive chemical preparation. Especially for biomedical imaging applications, the molecular vibrational resonances can serve as a contrast mechanism that does not require expensive and cumbersome reagent labeling steps.
