Design of output-graded narrow polychromatic filter by using photonic quasicrystals

A 1064 nm laser adaptive limiter with visible light transparency based on one dimensional photonic crystals of LiNbO3 defects

“…[17][18][19][20] Compared with two and three dimensional photonic crystals, one dimensional photonic crystals have been used in a wide range of applications such as optical sensors, optical switches, optical limiters, temperature sensors, and omni-directional high reflectors owing to their facile fabrication. [21][22][23][24] One dimensional photonic crystals, when employed as optical limiters, are nanoscale periodic optical structures capable of controlling and manipulating light, similar to the way semiconductors control electrons. 25 The characteristics of one dimensional photonic crystals exhibit considerable variation through manipulation of materials properties, including refractive index, layer count, and layer thickness.…”

Towards a highly efficient air purifier using annular photonic crystals in UV regimes

“…Moreover, a huge set of congurations from periodic to quasi-periodic have been studied to arrange PC materials. [18][19][20][21] PCs have been demonstrated in a massive number of applications in many different areas due to their outstanding properties. In this regard, PBG with high reectivity could be very useful for laser emissions, optical communication, photovoltaic panels, and waveguides.…”
