We experimentally demonstrate a novel approach based on adiabatic elimination scheme to control the coupling between densely packed waveguides. At the nano-scale, cancellation of the coupling between the waveguides can be achieved.
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.
We demonstrate that the optical force exerted on a suspended dielectric waveguide coupled to a metallic substrate is greatly enhanced compared to dielectric substrate, due to subwavelength optical energy confinement in the hybrid plasmonic mode.
We demonstrated the first directionally emitting deep sub-wavelength plasmon laser and circuit. The plasmon laser circuit naturally integrates photonic and electronic functionality allowing both efficient electrical modulation and wavelength multiplexing.
The optical loss of graphene can be tuned by shifting its Fermi level. We demonstrated that this tuning can be used for in a high-speed optical modulator at telecommunication wavelength.
We demonstrate Purcell enhancement of spontaneous decay rate up to 60 times and luminescence intensity up to five-fold from dye molecules strongly coupled to a non-resonant deep-subwavelength metal-dielectric hybrid plasmon waveguide.
Multi-core chips or chip multiprocessors (CMPs) are becoming the de facto architecture for scaling up performance and taking advantage of the increasing transistor count on the chip within reasonable power consumption levels. The projected increase in the number of cores in future CMPs is putting stringent demands on the design of the on-chip network (or network-on-chip, NOC). Nanophotonic interconnects...
We demonstrate a high-Q surface-plasmon-polariton (SPP) whispering-gallery microcavity with SPP Q factors up to 1,376 plusmn 65 in the near infrared. The SPP eigenmodes are accessed evanescently using a tapered optical waveguide.
We experimentally demonstrate cloaking at optical frequencies. A dielectric carpet cloak is designed to hide object under a curved reflecting surface by mimicking the reflection from a flat surface, enabling broadband invisibility with low loss.
