Ultrafast Nonlinear Microphotonics
Ultrafast Microphotonics Lab
In the Ultrafast Microphotnics Lab, we work at the intersection of ultrafast optics and integrated photonics. We explore nonlinear optical processes enabled by the tight confinement of light in micro- and nano-structured photonic devices to create novel chip-integrated light sources for emerging application in science and technology.

Self-injection-locked microcombs via synthetic reflection
15 January 2024
Self-injection locking to a photonic crystal ring-microresonator with synthetic reflection is demonstrated for the first time. The chip-integrated system does not rely on random imperfection-based backscattering and permits deterministic generation of single-soliton microcombs.
Sideband injection locking in microresonator frequency combs
12 December 2023
For many applications of microresonator frequency combs, the ability to control the comb's defining parameters is essential. Sideband-injection locking, a technique by which a secondary continuous-wave laser is injected into the microresonator, provides an elegant solution, enabling straightforward control of both the carrier-envelope offset frequency and repetition rate.
Femtosecond pulse amplification on a chip
08 November 2023
We recently demonstrated a 50x amplification of femtosecond pulses entirely on chip based Thulium as a gain medium. The achieved on-chip peak power levels exceed 800 W at pulse durations of 116fs.
