Optomechanical non-contact measurement of microparticle compressibility in liquids
Kewen Han, Jeewon Suh, Gaurav Bahl
High-throughput label-free measurements of the optical and mechanical properties of single microparticles play an important role in biological research, drug development, and relat…
Imaging of acoustic pressure modes in opto-mechano-fluidic resonators with a single particle probe
Jeewon Suh, Kewen Han, Gaurav Bahl
Opto-mechano-fluidic resonators (OMFRs) are a new platform for high-throughput sensing of the mechanical properties of freely flowing microparticles in arbitrary media. Experimenta…
Demonstration of a quantized microwave quadrupole insulator with topologically protected corner states
Christopher W. Peterson, Wladimir A. Benalcazar, Taylor L. Hughes +1
The modern theory of electric polarization in crystals associates the dipole moment of an insulator with a Berry phase of its electronic ground state [1, 2]. This concept constitut…
Breaking time-reversal symmetry with acoustic pumping of nanophotonic circuits
Donggyu B Sohn, Seunghwi Kim, Gaurav Bahl
Achieving non-reciprocal light propagation via stimuli that break time-reversal symmetry, without magneto-optics, remains a major challenge for integrated nanophotonic devices. Rec…
Optimization of Anisotropic Photonic Density of States for Raman Cooling
Yin-Chung Chen, Indronil Ghosh, André Schleife +2
Optical refrigeration of solids holds tremendous promise for applications in thermal management. It can be achieved through multiple mechanisms including inelastic anti-Stokes Bril…
