Description

Nanofabrication technology can be used to create chip-based optical resonators in which light is confined to wavelength-scale dimensions for thousands of optical cycles. The resulting large per photon intracavity field strength and long photon storage time, in combination with the device scalability and integration afforded by modern fabrication methods, provides several opportunities for applications in quantum and classical information processing, sensing, and metrology. We are working on multiple projects in characterizing light-matter interactions in chip-based nanophotonic structures in both the quantum and classical regimes.

In the quantum regime, research focuses on developing on- and off-chip methods for arbitrary control of single photon wave-packets, a potentially important resource for future hybrid quantum systems and for detection in wavelength regions for which low light level measurements is currently challenging. Photons generated by nanoscale emitters like a single quantum dot are spectrally and temporally shaped through processes such as frequency conversion, electro-optic modulation, and radiative rate inhibition/enhancement.

In the classical regime, we are utilizing cavity optomechanical systems to develop a new generation of sensors for atomic force microscopy, in which sub-picogram nanocantilever motion is transduced through near-field coupling to an optical microcavity. Both project areas involve the development of new measurement tools by which the light-matter interactions can be characterized and utilized, and fabrication of devices in the state-of-the-art CNST NanoFab. They also involve the opportunity for significant collaboration with other scientists and engineers within both CNST and NIST.
