Description | Informed by the requirements of future precision atomic clocks, this project targets the development of an "optical frequency comb" -- a laser providing a thousands of regularly spaced optical frequencies which form a ruler in frequency that is a critical component in quantum timekeeping devices. The main findings so far can be summarised as: (1) Development of a multi-GHz miniature fs lasers based on Yb-doped glass and ceramic gain media and directly diode-pumpable. (2) Super-continuum generation from integrated AlGaAs and Si-rich Si3N4 waveguides, incorporating coupling tapers and microring resonators |
Exploitation Route | Using the waveguides developed in this project it will be possible to achieve a supercontinuum that will span an octave allowing for the generation of an optical frequency comb. Using this comb we can transfer the high timing stability offered by the optical frequencies to the RF/microwave domain, which is a key component for developing a chip scale optical frequency atomic clock. This clock would have a huge impact on many different industrial sectors, such as Defence, Finance, Telecommunications and Geodesy. |
