Enhancement and speed-up of carrier dynamics in a dielectric nanocavity with deep sub-wavelength confinement
Gaoneng Dong, Ali Nawaz Babar, Rasmus Ellebæk Christiansen +4
The emergence of dielectric bowtie cavities enable optical confinement with ultrahigh quality factor and ultra-small optical mode volumes with perspectives for enhanced light-matte…
A nanolaser with extreme dielectric confinement
Meng Xiong, Yi Yu, Yury Berdnikov +5
The interaction between light and matter can be enhanced by spatially concentrating the light field to boost the photon energy density and increasing the photon dwell time to prolo…
Carrier diffusion in semiconductor nanoscale resonators
Marco Saldutti, Yi Yu, George Kountouris +2
It is shown that semiconductor nanoscale resonators with extreme dielectric confinement accelerate the diffusion of electron-hole pairs excited by nonlinear absorption. These novel…
Electrically-driven Photonic Crystal Lasers with Ultra-low Threshold
Evangelos Dimopoulos, Aurimas Sakanas, Andrey Marchevsky +5
Light sources with ultra-low energy consumption and high performance are required to realize optical interconnects for on-chip communication. Photonic crystal (PhC) nanocavity lase…
Nonreciprocal transmission in a photonic-crystal Fano structure enabled by symmetry breaking
Yi Yu, Yaohui Chen, Hao Hu +3
Nanostructures that feature nonreciprocal light transmission are highly desirable building blocks for realizing photonic integrated circuits. Here, a simple and ultra-compact photo…
