Photonics at sub-wave length scale

Xiang Zhang

President of University of Hong Kong
Compared with electronics that is already at nanoscale today, photonic circuits remain rather bulky due to optical diffraction limit. I will discuss physics in scaling down of photonics that is important for both optical sciences and modern information technology. We proposed a new optical cavity design using indefinite medium that exhibits an anomalous scaling law than conventional cavities which was confirmed experimentally. I will further present nanoscale waveguide and laser circuits using hybrid plasmons that can be multiplexed into a single waveguide-an effort towards integrated photonics at nano-scale. Finally, I will discuss non-Hermitian optics that is capable to sort color simultaneously at nano-scale for potential ultrahigh resolution camera.

Advancing Nanophotonics: From Tailorable Materials to Novel Phenomena

Alexandra Boltasseva

Purdue University
The recent advent of tailorable photonic materials such as plasmonic ceramics including transition metal nitrides (TMNs), MXenes, Weyl semimetals and transparent conducting oxides (TCOs) is currently driving the development of new concepts and devices for IT, communication, sustainable energy and quantum technologies. In addition to great tailorability of their optical properties, strong plasmonic behavior, optical nonlinearities, these materials offer pathways to uncovering new optical and quantum phenomena ranging from epsilon-near-zero behavior to transdimensional photonics and strongly correlated systems. In this talk, we explore novel applications of TMNs (titanium nitride, zirconium nitride) and TCOs for flat optics, all-optical switching, high-harmonic-based XUV generation as well as for demonstrating new physical effects in atomically thin, transdimensional plasmonic films related to strong light confinement and metal-to-insulator transition. Our work paves the way to novel phenomena and device design with ultrafast tunable and tailorable optical materials.

Extreme Space-Time Optics & Quantum Meta-Photonics

Vladimir M. Shalaev

Purdue University
We first discuss all-optical modulation with single photons using electron avalanche, resulting in record-high nonlinearities. Then we show that transparent conducting oxides (TCOs) operating in the near-zero index (NZI) regime can provide strong single-cycle modulation, thus enabling novel photonic time crystals. Finally, we discuss scalable quantum photonics with single-photon emitters in silicon nitride that we recently discovered as well as the intriguing possibility to generate indistinguishable single photons by using plasmonic speedup that could enable important quantum photonics applications, including quantum communication and quantum computing.

Miniaturized Spectrometers with Bandgap Engineering

Zhipei Sun

Aalto University
Miniaturized spectrometers, which can obtain incident spectra using a combination of device spectral responses and reconstruction algorithms, are essential for on-chip and implantable applications. Highly sensitive spectral measurement using a single detector allows the footprints of such spectrometers to be scaled down while achieving spectral resolution approaching that of benchtop systems. I will present our recent results on high-performance computational spectrometers with various bandgap engineering methods. Our approaches provide new routes toward ultra-miniaturization and offer unprecedented performance in accuracy, resolution, and operation bandwidth.

Topological photonic crystals realized using connected and nested structures

Che Ting Chan

Vice President of Hong Kong University of Science and Technology
We explore the physics of photonic crystals/meta-crystals, whose structure is determined by connectivity. We illustrate this concept with some examples. The first example focuses on a new type of photonic crystal comprising a 3D nested structure composed of co-axial waveguides that connect high-symmetry sites within a space group. These meta-crystals exhibit photonic dispersions similar to scalar waves while possessing vector-wave eigenvectors. This is intriguing because it is commonly believed that the electromagnetic modes in 3D photonic crystals must be explicitly solved as vector waves, rendering the scalar wave approximation inapplicable. However, the nested meta-crystal presents an exception, allowing 3D electromagnetic crystals to exhibit scalar wave dispersions. Consequently, designing topological photonic crystals becomes as simple as performing a tight-binding calculation. These 3D crystals also feature skyrmion-textured surface states with high quality factors within the light cone. We also explore how co-axial cable connected structures can be used to realize photonic non-Abelian topological charges. In these network systems, the bulk topological invariants manifest as non-integer quantities and exhibit non-Abelian properties in 3D or higher dimensions.

Plasmonic Terahertz Optoelectronics

Mona Jarrahi

UCLA
Although unique potentials of terahertz waves for chemical identification, material characterization, biological sensing, and medical imaging have been recognized for quite a while, the relatively poor performance, higher costs, and bulky nature of current terahertz systems continue to impede their deployment in field settings. In this talk, I will describe some of our recent results on developing new terahertz electronic/optoelectronic components and imaging/spectrometry architectures to mitigate performance limitations of existing terahertz systems. In specific, I will introduce new designs of high-performance photoconductive terahertz sources that utilize plasmonic nanoantennas to offer record-high optical-to-terahertz conversion efficiencies – demonstrating more than three orders of magnitude increase compared to the state of the art. I will describe that the unique capabilities of these plasmonic nanoantennas can be further extended to develop terahertz detectors and heterodyne spectrometers with quantum-level detection sensitivities over a broad terahertz bandwidth at room temperatures, which has not been possible through existing technologies. I will also present a terahertz time-domain imaging system based on a plasmonic photoconductive terahertz focal-plane array, which provides ultrafast-time-resolved and frequency-resolved amplitude and phase information of the imaged object with an imaging speed that exceeds 16 fps. The rich information provided by the terahertz focal-plane array allows super-resolving both shape and depth information of imaged objects with a lateral/depth resolution as small as 60/10 um and an effective number of pixels exceeding 1-kilo-pixels. These plasmonic antennas and device architectures are optimized for operation at telecommunication wavelengths, where very high power, narrow linewidth, wavelength tunable, compact and cost-effective optical sources are commercially available. Therefore, our results pave the way to compact and low-cost terahertz sources, detectors, spectrometers, and imaging systems that could offer numerous opportunities for e.g., medical imaging and diagnostics, atmospheric sensing, pharmaceutical quality control, and security screening systems.
