MD4.1 - INDISTINGUISHABLE ON-CHIP SINGLE-PHOTON SOURCES
Abstract
Abstract
Progress on integrating InGaAs quantum-dot single-photon sources within GaAs semiconductor photonic chips is reviewed. With resonant excitation, a radiative lifetime as short as 23 ps has been observed for a dot in a photonic-crystal nano-cavity, leading to single-photon emission with both high purity and indistinguishability.
MD4.2 - SPINNING RADIATION FROM TOPOLOGICAL INSULATORS
Abstract
Abstract
We show that thermal radiation from a topological insulator carries a nonzero average spin angular momentum.

Abstract
Abstract
In this paper, we experimentally study broadband perfect absorber based upon tungsten boride. We show that the absorptance of the WB perfect absorber has much better temperature stability when compared with an Al-based absorber: its absorptance changes little from 25° C to 270° C.

Abstract
Abstract
Nano-antennas on silica or semiconductor substrate cannot handle high power due to their low thermal conductivity. This paper shows that high thermal conductivity substrates such as diamond can handle 20 times higher fluence than silica substrate based nano-antenna without affecting their electrical field enhancement capacities.
MD4.5 - ANTIREFLECTION STRATEGY FOR NEAR-ZERO REFRACTIVE INDEX PHOTONIC CRYSTALS APPLICABLE TO AN ELEMENT-BY-ELEMENT FULL-RANK OPTICAL WIRELESS MIMO SYSTEM
Abstract
Abstract
We discuss an antireflection strategy for near-zero refractive index photonic crystals (PCs). Particularly, in 1 dimensional (1D) PCs, nearly polarization-independent angular selectivity with a transmission window around the normal direction emerges, allowing us to achieve high capacity in visible-light communications through element-by-element optical paths.
