Quantum Imaging & Sensing

Abstract
Infrared (IR) wavelengths are a range of great importance, particularly in the mid-IR region from 4000 cm-1 to 600 cm-1, where many molecules present their fingerprint properties. However, conventional IR spectroscopy and imaging methods suffer from the strong background noise of IR detectors. They often require cryogenic cooling, which leads to a high cost and limited sensitivity of the techniques.

In our group, we use the quantum interference phenomenon, which allows inferring the IR properties of a specimen from the detection of visible/near-IR light, where silicon detectors are broadly accessible. We perform IR spectroscopy and IR imaging measurements and show the applicability of the developed method for the sensing and bio-imaging applications.

Biography
Dr. Anna Paterova obtained her undergraduate degree in 2014 from Lomonosov Moscow State University, Physics department. From 2014 to 2018, she did Ph.D. research in Data Storage Institute A*STAR and Nanyang Technological University in Singapore with the support of SINGA A*STAR scholarship. In 2018, she obtained her Ph.D. degree at Nanyang Technological University in quantum optics and nonlinear interferometry. Since receiving her Ph.D., Anna has been working as a Research Scientist in the Institute of Materials Research and Engineering. Currently, her research interests include applying quantum optics and nonlinear interferometry in the problems of infrared spectroscopy and imaging.

Quantum Photonics Devices

Abstract
Quantum photonics platforms are a promising pathway for translating cutting-edge quantum technologies to practical and scalable devices. Here, we will present our work on photonics-integrated photodetectors for visible light, which will form an essential component of such platforms.

We will discuss the following aspects of device development:

  • Design and simulations.
  • Foundry fabrication.
  • Characterization of prototypes.
  • The pathway towards achieving the ultimate limit of single-photon sensitivity.
Biography
Dr. Victor Leong is focused on developing photonics devices to bring quantum technologies to real-world applications. Prior to joining A*STAR as a research scientist in 2016, he studied ultracold atoms for his Ph.D. at the Centre for Quantum Technologies (CQT) at the National University of Singapore (NUS). Victor obtained his Bachelor's degree from the University of Cambridge. He is a recipient of the A*STAR National Science Scholarship (NSS(BS)) and A*STAR Graduate Scholarship (AGS).
