Confining light on a chip: the science of optical micro-resonators
Like a tuning fork for light, optical resonators have a characteristic set of frequencies at which it is possible to confine light waves. At these frequencies, optical energy can be efficiently stored for lengths of time characterized by the resonator Q factor, roughly the storage time in cycles of oscillation.
In the last ten years there has been remarkable progress in boosting this storage time in micro and millimeter-scale optical resonators. Chip-based devices have attained Q factors of nearly 1 billion and micro-machined crystalline devices have achieved Qs exceeding 100 billion.
The long, energy-storage time and small form factor of these ultra-high-Q (UHQ) resonators enable access to an amazingly wide range of nonlinear phenomena and creation of laser devices with remarkable properties. Also, new science results from radiation-pressure coupling of optical and mechanical degrees-of-freedom in the resonators themselves.
We have created the highest Q-factor chip-based resonators and also launched many of the subjects of study in this field.
Our mission is to explore UHQ physics, investigate applications and create integrated UHQ systems.
