Electrically-Controlled Suppression of Rayleigh Backscattering in an Integrated Photonic Circuit
Ogulcan E. Orsel, Jiho Noh, Gaurav Bahl
Undesirable light scattering is an important fundamental cause for photon loss in nanophotonics. Rayleigh backscattering can be particularly difficult to avoid in wave-guiding syst…
Complete linear optical isolation at the microscale with ultralow loss
JunHwan Kim, Seunghwi Kim, Gaurav Bahl
Low-loss optical isolators and circulators are critical nonreciprocal components for signal routing and protection, but their chip-scale integration is not yet practical using stan…
Real-time sensing of flowing nanoparticles with electro-opto-mechanics
Jeewon Suh, Kewen Han, Christopher W Peterson +1
High-Q optical resonators allow label-free detection of individual nanoparticles through perturbation of optical signatures but have practical limitations due to reliance on random…
Role of Optical Density of States in Two-mode Optomechanical Cooling
Seunghwi Kim, Gaurav Bahl
Dynamical back-action cooling of phonons in optomechanical systems having one optical mode is well studied. Systems with two optical modes have the potential to reach significantly…
Non-Reciprocal Brillouin Scattering Induced Transparency
JunHwan Kim, Mark C. Kuzyk, Kewen Han +2
Electromagnetically induced transparency (EIT) provides a powerful mechanism for controlling light propagation in a dielectric medium, and for producing slow and fast light. EIT tr…
Opto-Acoustic Biosensing with Optomechanofluidic Resonators
Kaiyuan Zhu, Kewen Han, Tal Carmon +2
Opto-mechano-fluidic resonators (OMFRs) are a unique optofluidics platform that can measure the acoustic properties of fluids and bioanalytes in a fully-contained microfluidic syst…
