Monolithic Mode-Locked Lasers (MMLL)
The world’s first monolithic mode-locked lasers: among the quietest free-running optical oscillators available.
Research
Ultra-low-noise lasers, optical frequency combs and their applications in precision measurement.
We develop lasers and measurement techniques that push optical and microwave phase noise to its fundamental limits, and we use them for precision measurements. A full list of our papers is on the publications page.
Photonic Microwave Generation
Ultra-low phase noise microwaves from optical frequency division – made practical and reliable.
Ever wondered how short a yoctosecond is?
Measuring the timing jitter between optical pulse trains with yoctosecond-per-root-Hertz resolution.
Earlier projects
Ultra high-Q optical microresonators
Whispering-gallery-mode glass resonators with Q-factors beyond ten billion – thousands of times better than the best quartz crystals.
Chip-scale mode-locked lasers
Monolithic femtosecond sources based on integrated optics – towards fs-lasers on a chip.
Graphene-based optical materials & devices
Graphene saturable absorbers, electro-optic modulators and quantum interference control detectors – grown in our own CVD system.
