MB1.1 - ON THE PATH TO A HYBRID PEROVSKITE LASER DIODE
Abstract
Abstract
Electrically-pumped lasing remains a grand challenge for the organic electronics community. This talk will focus on developments toward this goal using organic-inorganic perovskite semiconductors, including optically-pumped cw lasing and light emitting diode cavity architectures that lase under optical pumping and reach current densities >0.5 kA/cm2.

Abstract
Abstract
Two different package structures of hybrid perovskite quantum dots light emitting diodes were demonstrated with stable and continuous light emission. With boron nitride nanoparticles, the lifetime of device is expected to be thousands of hours.
MB1.3 - THERMALLY CONTROLLABLE HIGH-EFFICIENCY UNIDIRECTIONAL COUPLING IN A DOUBLE-SLIT STRUCTURE FILLED WITH PHASE CHANGE MATERIAL
Abstract
Abstract
We present up to 80% coupling efficiency with extinction ratio of 1:800, tunable unidirectional launcher of surface plasmon polaritons in a double-slit structure filled with phase change materials at telecommunication wavelength for normally incident P-polarized light. Further more we achieved zero crosstalk.
MB2.1 - HIGH-SPEED QUANTUM PHOTONICS WITH PLASMONIC METAMATERIALS EMPOWERED BY MACHINE LEARNING
Abstract
Abstract
We outline future directions in the development of a platform for high-speed integrated quantum photonics, the use of plasmonics to outpace quantum decoherence and the application of machine-learning techniques for photonics designs and quantum optical measurements.

Abstract
Abstract
We present a compact folded metasurface optics platform that offers a low-cost and robust solution for the design and realization of compact optical systems. Specifically, we introduce the design and implementation of a miniature spectrometer and a hyperspectral imager as examples showcasing the platform potentials.
MB2.3 - EXCITATION OF EPSILON-NEAR-ZERO MODE IN OPTICAL FIBER
Abstract
Abstract
We demonstrate the excitation of epsilon-near-zero (ENZ) resonance on a side-polished optical fiber nano-coated with aluminum-doped zinc oxide (AZO) with vanishing permittivity at near-infrared wavelength. The ENZ resonance is caused by the coupling between guided modes supported by optical fiber and the AZO nanolayer.
MB3.1 - 2D MATERIAL INTEGRATED NANOPHOTONICS RESONATORS
MB3.2 - SPECTROSCOPY OF QUANTUM EMITTERS IN TWO-DIMENSIONAL H-BN
Abstract
Abstract
In this talk, we discuss our recent experiments on the spectral response under applied strain of quantum emitters based on structural defects in hBN. We also report on photoluminescence excitation experiments that allow to identify the vibronic excited states associated to their characteristic energy level structure.
MB3.3 - FIELD ENHANCEMENT OF EPSILON-NEAR-ZERO MODES IN ATOMIC-LAYER-DEPOSITED ZNO:AL NANOLAYERS
Abstract
Abstract
We derive an expression for electric-field intensity enhancement due to the epsilon-near-zero modes in ultra-thin conducting layers. We show that absorptance and field enhancement in aluminum-doped zinc oxide nanolayers grown by atomic layer deposition are controlled by nanolayer thickness and optical losses.
MB4.1 - ENGINEERING LASER COHERENCE AND ITS APPLICATIONS
Abstract
Abstract
We have developed random lasers and wave-chaotic microcavity lasers with low spatial coherence to achieve speckle-free full-field imaging. We have also invented a fast and efficient method of switching the spatial coherence of a degenerate cavity laser for bimodal microscopy.

Abstract
Abstract
A single multimode interference waveguide is used to create distinct spectral spot patterns on two liquid-core waveguides on an optofluidic chip. This device is used for multiplexed detection of antibiotic-resistant plasmids with single nucleic acid sensitivity.
MB4.4 - HYBRID PLASMONIC SENSOR FOR THE DETECTION OF NEUROTRANSMITTERS DIRECTLY FROM THE BLOOD
