Seeing a ghost: hybrid waves in anisotropic crystals

Baranov, Denis

2019 Advanced Photonics

doi:10.1117/1.AP.1.4.040501

Abstract.A new kind of electromagnetic wave, combining the properties of propagating and evanescent waves, is discovered theoretically in a paper by E. Narimanov, published in this issue of Advanced Photonics. The commentary provides context for Narimov’s paper.

Class-specific differential detection in diffractive optical neural networks improves inference accuracy

Li, Jingxi; Mengu, Deniz; Luo, Yi; Rivenson, Yair; Ozcan, Aydogan

2019 Advanced Photonics

doi:10.1117/1.AP.1.4.046001

Abstract.Optical computing provides unique opportunities in terms of parallelization, scalability, power efficiency, and computational speed and has attracted major interest for machine learning. Diffractive deep neural networks have been introduced earlier as an optical machine learning...

Ghost resonance in anisotropic materials: negative refractive index and evanescent field enhancement in lossless media

Narimanov, Evgenii

2019 Advanced Photonics

doi:10.1117/1.AP.1.4.046003

Abstract.We show that dielectric waveguides formed by materials with strong optical anisotropy support electromagnetic waves that combine the properties of propagating and evanescent fields. These “ghost waves” are created in tangent bifurcations that “annihilate” pairs of positive- and...

Air-core fiber distribution of hybrid vector vortex-polarization entangled states

Cozzolino, Daniele; Polino, Emanuele; Valeri, Mauro; Carvacho, Gonzalo; Bacco, Davide; Spagnolo, Nicolò; Oxenløwe, Leif K.; Sciarrino, Fabio

2019 Advanced Photonics

doi:10.1117/1.AP.1.4.046005

Abstract.Entanglement distribution between distant parties is one of the most important and challenging tasks in quantum communication. Distribution of photonic entangled states using optical fiber links is a fundamental building block toward quantum networks. Among the different degrees of...
