Phase Modulation of Photonic Band Gap Signal. [PDF]
Sci Rep, 2016 AbstractWe first investigate the probe transmission signal (PTS) and the four wave mixing band gap signal (FWM BGS) modulated simultaneously by the relative phase and the nonlinear phase shift in the photonic band gap (PBG) structure. The switch between the absorption enhancement of PTS and the transmission enhancement of PTS with the help of changing ...

Titania Photonic Crystals with Precise Photonic Band Gap Position via Anodizing with Voltage versus Optical Path Length Modulation [PDF]
Nanomaterials, 2019 Photonic crystals based on titanium oxide are promising for optoelectronic applications, for example as components of solar cells and photodetectors. These materials attract great research attention because of the high refractive index of TiO2.

Hydrogen production by tuning the photonic band gap with the electronic band gap of TiO₂. [PDF]
Sci Rep, 2013 Tuning the photonic band gap (PBG) to the electronic band gap (EBG) of Au/TiO(2) catalysts resulted in considerable enhancement of the photocatalytic water splitting to hydrogen under direct sunlight. Au/TiO(2) (PBG-357 nm) photocatalyst exhibited superior photocatalytic performance under both UV and sunlight compared to the Au/TiO(2) (PBG-585 nm ...

An Optical Probe of a 3D Photonic Band Gap [PDF]
2019 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2019 There is a wide interest in three-dimensional (3D) photonic crystals that radically control the spontaneous emission of embedded quantum emitters and cavity QED, control thermal emission, allow for efficient miniature lasers, or efficient photoelectric conversion in solar cells [1,2].

Photonic Band Gap Materials [PDF]
Proceedings of European Meeting on Lasers and Electro-Optics CLEOE-96, 1996 It is now some time since Yablonovitch proposed the optical analogue of the electron band gap: periodically structured dielectrics may totally exclude light in certain frequency ranges. At the time this concept of a ‘phtonc insulator’ provoked a furore and not a little disbelieve, but the concept is now an accepted one and the attention of the ...

Results in Physics, 2023 Traditionally, in the application of photonic crystals, defect modes are mostly introduced in the photonic band gap to realize high-performance waveguides, and electromagnetic waves beyond the photonic band gap cannot be controlled in photonic crystals ...
