Abstract
In this study, we investigate how an external magnetic field that can have any
direction affects a superlattice’s photonic band structure, composed of alternating dielectric and
plasma layers. By deriving the dispersion equations, we show that the photonic spectrum of the
superlattice loses its degeneracy and splits into two branches due to the external magnetic field.
Moreover, our findings reveal a direction-independent transition from a photonic insulator to
a photonic conductor. Interestingly, our results indicate that a superlattice that was previously
completely photo-isolating can become entirely photo-conducting, regardless of the direction of
the external magnetic field.
期刊介绍:
Rapid progress in optics and photonics has broadened its application enormously into many branches, including information and communication technology, security, sensing, bio- and medical sciences, healthcare and chemistry.
Recent achievements in other sciences have allowed continual discovery of new natural mysteries and formulation of challenging goals for optics that require further development of modern concepts and running fundamental research.
The Journal of the European Optical Society – Rapid Publications (JEOS:RP) aims to tackle all of the aforementioned points in the form of prompt, scientific, high-quality communications that report on the latest findings. It presents emerging technologies and outlining strategic goals in optics and photonics.
The journal covers both fundamental and applied topics, including but not limited to:
Classical and quantum optics
Light/matter interaction
Optical communication
Micro- and nanooptics
Nonlinear optical phenomena
Optical materials
Optical metrology
Optical spectroscopy
Colour research
Nano and metamaterials
Modern photonics technology
Optical engineering, design and instrumentation
Optical applications in bio-physics and medicine
Interdisciplinary fields using photonics, such as in energy, climate change and cultural heritage
The journal aims to provide readers with recent and important achievements in optics/photonics and, as its name suggests, it strives for the shortest possible publication time.
