Summary
This review explores unique polarization-degenerate band gaps in one-dimensional photonic crystals. It details their formation, properties, and impact on crystal spectra, including frozen modes and optical effects.
Area of Science:
- Condensed matter physics
- Optics and photonics
- Materials science
Background:
- One-dimensional photonic crystals exhibit unique spectral properties.
- Anisotropic and magnetooptic materials introduce complex behaviors in photonic crystals.
- Specialized band gaps, such as polarization-degenerate band gaps, warrant detailed investigation.
Purpose of the Study:
- To review the spectral characteristics of one-dimensional photonic crystals composed of anisotropic and/or magnetooptic materials.
- To focus on the formation, properties, and implications of polarization-degenerate band gaps.
- To analyze the interplay between different band gaps and their influence on photonic crystal spectra.
Main Methods:
- Theoretical analysis of photonic crystal spectra.
- Investigation of band gap formation mechanisms.
- Examination of spectral peculiarities arising from band gap linkage.
Main Results:
- Detailed analysis of polarization-degenerate band gaps in anisotropic/magnetooptic photonic crystals.
- Demonstration that the linkage between Brillouin and degenerate band gaps causes frozen modes.
- Analysis of the optical Borrmann effect at degenerate band gap boundaries and optical Tamm states within them.
Conclusions:
- Polarization-degenerate band gaps significantly influence the spectral properties of one-dimensional photonic crystals.
- The linkage between different band gaps leads to unique phenomena like frozen modes.
- Further understanding of these band gaps and associated effects is crucial for photonic device applications.

When two or more atoms come together to form a molecule, their atomic orbitals combine and molecular orbitals of distinct energies result. In a solid, there are a large number of atoms, and therefore a large number of atomic orbitals that may be combined into molecular orbitals. These groups of molecular orbitals are so closely placed together to form continuous regions of energies, known as the bands.
The energy difference between these bands is known as the band gap.

Isolated atoms have discrete energy levels that are well described by the Bohr model. And, it quantifies the energy of an electron in a hydrogen atom as En. Higher quantum numbers 'n' yield less negative, closer electron energy levels.
Band Formation:
When atoms are brought close together, as in a solid, these discrete energy levels begin to split due to the overlap of electron orbitals from adjacent atoms. This split occurs because of the Pauli exclusion principle, which states...

There is variation in the electrical conductivity of materials - metals, semiconductors, and insulators that are showcased with the help of the energy band diagrams.
Metals such as copper (Cu), zinc (Zn), or lead (Pb) have low resistivity and feature conduction bands that are either not fully occupied or overlap with the valence band, making a bandgap non-existent. This allows electrons in the highest energy levels of the valence band to easily transition to the conduction band upon gaining...

The vacuum level denotes the energy threshold required for an electron to escape from a material surface. It is usually positioned above the conduction band of a semiconductor and acts as a benchmark for comparing electron energies within various materials.
Electron affinity in semiconductors refers to the energy gap between the minimum of its conduction band and the vacuum level and it is a critical parameter in determining how easily a semiconductor can accept additional electrons.

Crystal Field Theory
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.

The Fermi-Dirac function is represented by an S-shaped curve indicating the probability of an energy state being occupied by an electron at a given temperature. The Fermi level is the energy level at which there is a fifty percent chance of finding an electron, and it is positioned between the lower-energy valence band and the higher-energy conduction band.
At absolute zero temperature, electrons fill all energy states up to the Fermi level, leaving upper states empty. As the temperature rises,...
