Periodic Reporting for period 1 - ShaMROCk (Superconductive MiR phOton Counter)
Reporting period: 2018-06-01 to 2020-05-31
Even though competitive SPD technologies are available for the visible and in the near-infrared range, the mid-infrared (MIR) spectral region lacks in a performant analogue. A detector able to register individual photons in this wavelength range (2.5-25μm) would be extremely desirable for many areas of technology and science, from analysis in industry to advanced research applications. In the MIR spectral range reside vibrational modes of several molecules as well as fundamental absorption bands of gases, intersubband transitions in quantum wells and specific fingerprints of chemical species. A detector sensible at single photon level would greatly boost the field of vibrational and MIR spectroscopy.
By taking advantage of superconducting nanowire SPDs (SNSPDs), the goal of ShaMROCk is to realize an efficient, fast and accurate SPD operating in the MIR with a minimum number of dark counts. This tantalizing perspective can be reached by merging SNSPD technology with Silicon Carbide (SiC) photonics. Due to the presence of quantum emitters, the development of SNSPDs on top SiC photonic components is additionally important as this material is emerging as scalable platform for quantum information processing with photons.
