Analysis of 1 Dimensional Photonic Crystal Optical Limiters
Keywords:Optical limiter, defect layer, photonic crystal, Non-linear.
Most of the optical limiting mechanisms depend upon substances with nonlinear optical responses that allow
light to regulate light and are gaining popularity once again. The realisation of innovative optical limiters
functioning for extremely low limiting threshold and high damage threshold throughout a larger domain is
advantageously facilitated by one-dimensional photonic crystals (1D PhC). Researchers have extensively studied
1D PhC, a periodic nanostructure having a refractive index distribution along one direction. Unfortunately, there
is little evidence in the research community of their usefulness in limiting high-intensity radiation to safeguard
expensive optical sensors and systems. Here, a summary of the theoretically suggested, computationally
simulated, mathematically modelled, and empirically realised 1D PhC reflecting optical limiters is given. This
review focuses on the limited but noteworthy examination of optical systems based on 1D photonic crystals.
