High-frequency cavity optomechanics using bulk acoustic phonons
Prashanta Kharel, Glen I. Harris, Eric A. Kittlaus +4
To date, micro- and nano-scale optomechanical systems have enabled many proof-of-principle quantum operations through access to high-frequency (GHz) phonon modes that are readily c…
Nonreciprocal Inter-band Brillouin Modulation
Eric A. Kittlaus, Nils T. Otterstrom, Prashanta Kharel +2
Achieving nonreciprocal light propagation in photonic circuits is essential to control signal crosstalk and optical back-scatter. However, realizing high-fidelity nonreciprocity in…
Optomechanical cooling in a continuous system
Nils T. Otterstrom, Ryan O. Behunin, Eric A. Kittlaus +1
Radiation-pressure-induced optomechanical coupling permits exquisite control of micro- and mesoscopic mechanical oscillators. This ability to manipulate and even damp mechanical mo…
Ultra-high-Q phononic resonators on-chip at cryogenic temperatures
Prashanta Kharel, Yiwen Chu, Michael Power +3
Long-lived, high-frequency phonons are valuable for applications ranging from optomechanics to emerging quantum systems. For scientific as well as technological impact, we seek hig…
Creation and control of multi-phonon Fock states in a bulk acoustic wave resonator
Yiwen Chu, Prashanta Kharel, Taekwan Yoon +3
Quantum states of mechanical motion can be important resources for quantum information, metrology, and studies of fundamental physics. Recent demonstrations of superconducting qubi…
Sub-Hz Linewidth Photonic-Integrated Brillouin Laser
Sarat Gundavarapu, Ryan Behunin, Grant M. Brodnik +4
Photonic systems and technologies traditionally relegated to table-top experiments are poised to make the leap from the laboratory to real-world applications through integration. S…
Fundamental noise dynamics in cascaded-order Brillouin lasers
Ryan Behunin, Nils T. Otterstrom, Peter T. Rakich +2
The dynamics of cascaded-order Brillouin lasers make them ideal for applications such as rotation sensing, highly coherent optical communications, and low-noise microwave signal sy…
Integrated RF-photonic Filters via Photonic-Phononic Emit-Receive Operations
Eric A. Kittlaus, Prashanta Kharel, Nils T. Otterstrom +2
The creation of high-performance narrowband filters is of great interest for many RF-signal processing applications. To this end, numerous schemes for electronic, MEMS-based, and m…
