Enhanced Photon-Emitter Coupling in Micro/Nano Photonic Structures

Qi Zhang, Qihuang Gong, Ying Gu

The strong confined electromagnetic field in the micro/nano photonic structures brings new opportunities for the research of interaction between light and matter. By designing optical modes, light can be controlled to realize reversible or inreversible energy exchange between photons and emitters at the micro/nano scale. Here, we review the basic principles of the interaction between light and matter in cavity quantum electrodynamics and their recent advances in strong coupling based on micro/nano photonic structures such as plasmon nanostructures, whispering gallery resonators and photonic crystals. These works opening the research of quantum nanophotonics will have great influence on the on-chip quantum devices and quantum informations.The strong confined electromagnetic field in the micro/nano photonic structures brings new opportunities for the research of interaction between light and matter.

Nano-optical measurements of novel superconducting single photon detector designs

Robert M. Heath, Michael G. Tanner, L. San Emeterio Alvarez +4 more

Superconducting nanowire single photon detectors (SNSPDs) are a highly promising emerging photon counting technology, offering infrared sensitivity combined with low dark count rates and sub-100 ps timing jitter [1]. These devices are under consideration for a wide variety of photon counting applications, from quantum cryptography to remote sensing. Next generation device designs based on optical cavities, ultra narrow wires, parallel wire arrays and nano-antenna enhanced devices are being evaluated to meet the demands of advanced photon counting applications.Superconducting nanowire single photon detectors (SNSPDs) are a highly promising emerging photon counting technology, offering infrared sensitivity combined with low dark count rates and sub-100 ps timing jitter [1].

A new platform for atom-light interactions on the nano-scale

William Hamlyn

We present the design, fabrication, and operation of a new genera-tion of thermal alkali vapour nano-cells. The nano-cells include in-ternal structures with length scales 200−2000 nm created by laserlithography and reactive ion etching. The assembly process adoptsoptical contact bonding and glassblowing, avoiding the requirementfor any bonding agents or adhesives. We demonstrate a novel methodfor characterising the size of the internal vapour nano-channels. Thedesign allows for greater optical access and compatibility with highnumerical aperture (NA=0.7) optics; we demonstrate this with totalinternal reflection fluorescence spectroscopy and high resolution ima-ging of the nano-channels. Additionally, we report for the first time onthe photon statistics of light from a thin atomic ensemble. Finally, wediscuss the diffusion of atoms inside confined geometries with a num-ber of detection methods, and investigate options for controlling andmanipulating the atomic density and its diffusion. In total, we presentour new nano-cell design as a significant advancement of the field andpropose its use in scalable atomic and quantum optics applications andtechnologies.We present the design, fabrication, and operation of a new genera-tion of thermal alkali vapour nano-cells.
