Optical Frequency Combs in Surface Nanoscale Axial Photonic Microresonators

This project aims to explore the generation of optical frequency combs (OFCs) in a surface nanoscale axial photonic microresonator (SNAPR). A SNAPR is an optical device created by modifying the radius of an optical fibre. This modification enables the trapping of light within the device, enhancing its intensity and leading to more pronounced optical effects.

One such effect is the generation of OFCs. An OFC is a pattern of light made up of multiple, evenly spaced lines across a spectrum. Under very specific conditions the incoming light does not exit the device with the same wavelength that was input. Instead, the device generates a series of evenly spaced spectral lines. These spectral lines can then be used as a hyper-precise ruler. This process of frequency comb generation is complex and not straightforward, and the goal of this project is to perform a detailed study of this phenomenon in SNAPRs.

The collaboration between Dr. Del’Haye’s and Prof. Bianucci’s research groups will strengthen their work in microphotonics and specifically nonlinear optics. This project will also provide valuable hands-on experience for the intern and foster future collaborations between the two research groups, advancing the field of optical technologies.
