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.

MB3.4 - PHOTO-DETECTOR BASED ON MOS2/GRAPHENE/AU SCHOTTKY BARRIER

Abstract

Abstract

We report a photo-detector based on MoS2/Graphene/Au Schottky barrier. A monolayer graphene is inserted between the MoS2 and Au to achieve an abrupt Schottky contact. A high-performance photo-detector has been successfully implemented.

Abstract

Abstract

Increasing network centralization and the proliferation of radio x-haul over fiber will lead to the effective convergence of optical networks - previously considered to be distinct. This work proposes system-level design considerations and requirerments for network convergence and wired/wireless service co-existence in future optical access.

Abstract

Abstract

We review the role of optical fiber as a transport medium in the three generations of in-building wireless networks. We show that fiber becomes a necessity for 5G radio access networks (RAN) operating in high-bandwidth regions of the spectrum at millimeter wave (mmWave) frequencies.

Abstract

Abstract

This paper proposes a novel cancellation technique of a Fresnel reflected light in single-wavelength bidirectional wavelength division multiplexed passive optical network (WDM-PON) transmission system. We experimentally confirmed error vector magnitude (EVM) and bit error rate (BER) improvements in comparison with no cancellation case.

Abstract

Abstract

Exceptional nanophotonics, creating quantum symmetry on-a-chip and utilizing its associated topology, enables novel photonics functionalities. In particular, I will discuss an orbital angular momentum microlaser and non-Hermitian topological photonics for robust yet flexible photonic integrated circuits and laser sources for optical communication and computing.
