We will review our recent progress in dynamically buffering, trapping, dropping and sorting particles on silicon nitride optofluidic circuits. We will also discuss particle transport and sensing on silicon nitride coupled-resonator optical waveguides.
Knowing the mode structure of light aids in minimizing loss and decoherence of quantum information. We present and experimentally implement reconstruction of the mode distributions of classical and non-classical light using measured photon number distributions.
We demonstrate a new type of electrically tunable strong coupling between a planar metamaterial layer and an ultra-thin epsilon-near-zero layer made of a doped semiconductor. This can find novel applications in chip-scale infrared optoelectronic devices.
An optical fiber taper placed in the near field of a “split-beam” photonic crystal nanobeam cavity with a physical gap at the cavity center breaks the system's vertical dielectric symmetry, enabling selective optomechanical coupling to multiple cantilever resonances using a single optical nanocavity mode.
We present ultra-strong light-matter interaction of a metamaterial mode and an intersubband transition for normal incidence radiation in the mid-infrared spectral region. The anti-crossed lines show a splitting of 15% of the central frequency.
We study asymmetric double InGaAs quantum well samples, featuring three different barrier widths, using optical two-dimensional Fourier transform spectroscopy. Depending on the barrier width, we observe different coupling mechanisms between the two wells.
We report on the observation of confined coherent acoustic plasmon waves in photoexcited GaAs using ultrafast pump probe experiments. Results are in good agreement with theoretical predictions under the random phase approximation.
A 150 μm2 45 Gb/s SOI-DPSK demodulator maintains good performance (ER>17 dB, BER<10−9) over 6.5% variation in the core length of 1×2 MMI couplers for single ended photodetection and 3 dB power penalty/0C variation in temperature.
A guided-wave silicon optical bench with monolithic 45˚ micro-reflector for 3-D integrated optical interconnect is experimentally demonstrated. Optical coupling-efficiency between VCSEL and PIN PD is −1.74dB with 10mA bias, and detector current is 1.22mA.
We show that the use of a coupled cavity or a bimodal cavity can improve single photon generation significantly relative to a single quantum dot strongly coupled to a cavity.
We present spectra evolution of photonic molecules upon individual or collective coupling of supermodes in one resonator with single mode in the other one by tuning the coupling strength and spectral overlap of the modes.
A pulsed scheme for generating two-mode squeezed light via the coupling of two optical modes to a mechanical oscillator in an optomechanical system is proposed. The scheme can be robust against thermal mechanical motion.
By mixing three nearly-even-spaced optical frequencies generated by coupled optical parametric oscillators based in KTP stacks and bulk KTP in a nonlinear medium, we demonstrate coherent interference of THz waves.
We investigate the nano-optomechanical properties between a nanowire and a focused beam of light. Based on such a system, we report unprecedently sensitive vectorial detection of nanomechanical motion using SiC nanowires and Carbon nanotubes.
Giant optical propelling velocities of 15–20 μm polystyrene microspheres are observed in evanescent fiber-taper-to-microsphere couplers. The results demonstrate a possibility of parallel particle-sorting according to the frequency of their whispering gallery mode resonances.
Through experimental study of an array of coupled photonic crystal cavities, we find that the intercavity coupling is significantly larger than the fabrication-induced disorder, a necessary condition for the generation of strongly correlated photons.
We demonstrate a single emitter all-dielectric QED system that concentrates light at nanometer scale. The emitter exhibits a record high 31-fold emission enhancement with strongly suppressed blinking. 80% of emission couples into a waveguide mode.
Simulation of quasi-phase-matching processes for ultrafast pulses in an intra-cavity pumped OPO is presented. Results reveal an effective cross phase modulation which introduces the coupling between OPO and pump cavities.
We demonstrate electromagnetically induced transparency and wavelength conversion between 980 nm and 1300 nm bands in Si3N4 microdisk optomechanical resonators, through radiation pressure coupling of multiple high-Q optical modes with a mechanical mode.
We develop an all-integrated optoelectromechanical system that operates up to 4.20 GHz. The in-plane bulk acoustic modes of a photonic crystal membrane are electrocapacitively actuated and optically detected by a high-Q slotted photonic crystal cavity.
