Untangling the issues with miniaturisation of optical frequency combs
Optical frequency combs are extremely precise tools to measure frequencies or changes in frequencies. Ultrafast lasers are used to emit a continuous train of very brief, closely spaced pulses of light. The spectrum results in evenly spaced hair-like ‘teeth’ resembling a comb. Aside from more accurate atomic clocks, frequency combs could easily find application in fields relying on identification or manipulation of atoms and molecules such as environmental toxicology and quantum computing. However, most commercially available systems still rely on large and expensive lasers and they are primarily used in metrology and physics. REFOCUS plans to deliver chip-scale miniaturised optical combs and open the door to portable, cost-effective systems for applications in chemical sensing, communications and medical imaging.
