Frequency combs, solitons and four-dimensional photonics with micro-resonators
This is a computational and theoretical PhD project that aims to study generation of ultrabroad frequency spectra (frequency combs) in micro-ring and other multimode resonators. Project will focus on temporal and spatio-temporal solitons associated with the comb generation in micro-resonators as well as designing a synthetic fourth dimension in frequency space in the resonator arrays.
Optical frequency combs provide highly accurate frequency rulers for the metrology and spectroscopy applications and enable researchers to further study nonlinear and quantum nature of light matter interaction in structured environment. One of the current trends in the area of comb generation is to move from large laser systems to small micro-resonator based comb schemes, where light matter interaction is significantly enhanced and nonlinear effects can become more pronounced. Manipulating by the intermodal coupling in the resonator arrays one can create an artificial dimension. Using this planar photonic devices can be made effectively 3 dimensional, while 3D structures can be made 4 dimensional, thereby opening up a new realm of optics and nonlinear physics in a four-dimensional space. A particular focus of the project will be to enrich knowledge about solitons and nonlinear effects in micro-resonators and their arrays using new types of optical nonlinearities due to cascaded quadratic and exciton-polariton interaction processes.
