** TALK CANCELLED** Toward Longer-wavelength Optical Quantum Communications
Thu, 19/01/2023 - 13:00
Location:
Speaker:
Dr Adetunmise Dada
Affiliation:
University of Glasgow
Synopsis:
This seminar will be followed by tea and coffee in the DB crush area.
Synopsis:
The spectral region above 2 microns is rapidly becoming highly promising for optical communications with significant potential advantages over the traditional telecom C-band (1550 nm). This makes it crucial to develop and investigate quantum light sources and measurement capabilities at longer wavelengths. For example, the 2.1-μm band has been demonstrated to have minimal losses in the hollow-core photonic band gap fibre (HCF), which is an emerging transmission-fibre alternative due to providing the lowest available latency and its ultra-low nonlinearity. In addition, although the 2.1-μm band enjoys similar atmospheric transparency as the telecom C-band, the solar background is up to 3 times lower, making it especially promising for free-space optical communications during daytime. Also, wavelengths further beyond the 2.1-μm band can offer dramatically improved penetration of light cloud, haze and fog. In this talk, I will present some of our recent work toward developing quantum light sources and measurement capabilities for longer-wavelength quantum communications.
Biography:
Adetunmise Dada is a Lecturer in the School of Physics and Astronomy, University of Glasgow. He has over 9 years of postdoctoral research experience in experimental quantum photonics using semiconductor quantum-dot-based on-demand single-photon sources as well as parametric sources of photon pairs. His past roles include Research Fellow within the Electronics and Nanoscale Engineering Research Division in the School of Engineering at the University of Glasgow (-2021), Senior Research Associate within the Quantum Engineering Technology Labs (2016-2019) at the University of Bristol, and Research Associate in the Quantum Photonics Laboratory at Heriot-Watt University (2013 - 2016).
