Project description
A compact, efficient system for optical frequency combs
Optical frequency combs (OFCs) are key tools for precision, timing and navigation applications. With the support of the Marie Skłodowska-Curie Actions programme, the IMCSC project plans to create a chip-scale system that makes it easier to detect important radio frequency signals from OFCs. Researchers will consider two materials for use: silicon nitride, which proved excellent in generating wide-ranging light combs, and thin-film lithium niobate (TFLN), which helps with converting and modulating frequencies. By integrating these materials on a single chip, researchers will develop a power-efficient, broadband microcomb system. Project activities will also include a new photonic molecule structure for better light generation, TFLN waveguide poling and a unified chip design for compact, high-performance OFC applications.
Objective
Optical frequency combs (OFC) play an essential role in precision, timing and navigation applications. Integrated photonics facilities the development of OFC-based applications towards chip-scale miniature package. Most applications require detecting the radio frequency (RF) signals of a OFC (i.e. repetition rate and carrier-envelope offset frequency). Thus, an important step towards miniaturized complex OFC systems is to integrate the OFC generation with the auxiliaries components required for detecting its RF signals onto the same chip. This project aim to develop an integrated microcomb system chip with accessible RF signals detection using heterogeneously integrated photonic platforms. Silicon nitride (SiN) platforms have shown their superiority in comb generations using microresonators (i.e. microcomb), with octave-spanning spectrum and dispersive wave emissions that enable detection of the carrier-envelope offset frequency via f-2f self-referencing process. Thin-film lithium niobate (TFLN) platforms are advantageous in second-order nonlinear frequency conversions and electro-optics modulations, the former can be applied for the f-2f process, while the latter is widely used for frequency down-converting the high-frequency repetition rate of a microcomb. Therefore, this project will explore heterogeneous integration technique to combine the SiN microcomb generator with TFLN devices for f-2f process and frequency down-conversion on a single chip. Specially, a novel photonic molecule structure will be explored for power-efficient octave-spanning microcomb generation with strong dispersive wave emission. A broadband electro-optics frequency comb will be developed for frequency down-conversion of microcomb repetition rate. Periodically poling of TFLN waveguide will be explored for frequency doubling in f-2f process. Heterogeneous integration will bring together all these components to deliver an integrated microcomb system.
