Projects and Programs

Far-infrared Spectroscopy of Biomolecules (Archived)

Completed

We employ novel complimentary measurement and theoretical techniques to explore the low frequency intramolecular dynamics of model biological molecules including amino acids, short peptides with constrained structures, proteins with well-defined tertiary structures and DNAs. Our current efforts

Platform for Realizing Integrated Molecule Experiments (PRIME)

Ongoing

Blackbodies realize a clear relationship between radiated power and temperature through Planck’s law. While a reliable instrument for temperature and power calibrations, blackbodies are afflicted with a plethora of systematics (e.g., non-ideal emissivity, propagation loss, temperature gradients

Micro- and nano-optomechanical systems

Ongoing

Our primary current research direction involves the use of fabricated devices with sub-wavelength periodicity (photonic crystals) as optomechanical elements. Such structures enable a rich variety of devices, including mirrors, polarizers, and filters, in a configuration that couples naturally to

Hybrid Quantum Optomechanical Systems with Solid-State Artificial Atoms

Ongoing

Quantum Dot – Surface Acoustic Wave Microwave-to-Optical Transducers In this project, we focus on coupling nanoscale acoustic resonators with InAs quantum dot (QD) single photon sources (Fig. 1). At ultra-low temperatures, such as those in a dilution refrigerator, the acoustic resonators act as
