Project Description

Ultra-High-Q microresonators enable the confinement of extremely high levels of optical power into tiny micron-scale volumes. This allows to observe nonlinear optical effects at extremely low threshold powers, making microresonators ideal components for future generations of integrated photonic circuits and for optical computing.

One key application that utilises nonlinear optics in microresonators is the generation of optical frequency combs [1]. Optical frequency combs have become ubiquitous tools for spectroscopy, precision metrology and optical clocks and their discovery was rewarded with the Nobel Prize in 2005. Microresonators have recently been shown to be promising candidates for shrinking optical frequency comb generators into chip-based devices for out-of-the-lab use [2]. However, the underlying physics of optical comb generation in microresonators is not fully understood and the physical principles are currently under investigation.

There is an opportunity for one doctoral students to join a recently established research team at the National Physical Laboratory (NPL) to work on microresonator-based frequency comb generation. The research project can be both on the applied side of frequency comb generation in microresonators as well as on the fundamental research side with the goal of understanding the physics of the underlying comb generation process. NPL provides an ideal environment for these projects with an existing infrastructure of optical atomic clocks and conventional frequency combs.
