Nonlinear optics of photonic hyper-crystals: optical limiting and hyper-computing [PDF]
Photonic hyper-crystals combine the most interesting features of hyperbolic metamaterials and photonic crystals. Since the dispersion law of extraordinary photons in hyperbolic metamaterials does not exhibit the usual diffraction limit, photonic hyper-crystals exhibit light localization on deep subwavelength scales, leading to considerable enhancement ...

Dynamics simulation of photonic crystal fiber end face polishing
The high quality of polished end face of photonic crystal fiber has a significant effect on coupling efficiency when photonic crystal fiber is used to couple with other optical devices. In order to obtain the smooth surface of the photonic crystal fiber,

Metallo-Dielectric Photonic Crystals and Bandgap Blue-Shift [PDF]
One of the most appealing aspects of photonic crystal structures is the photonic bandgap created in structures with sufficiently high dielectric contrasts between constituent materials. Understanding how specific photonic crystal structures and their associated stopband positions can selectively interfere with incoming light is vital for implementing ...

Loss analysis of air-core photonic crystal fibers [PDF]
By using a multipole moment approach, we analyze the loss of an air-core photonic crystal fiber and demonstrate that it is possible reduce the transmission loss that is due to photon radiation leakage through the photonic crystal cladding to a level ...

Lasing Spaser in Photonic Crystals [PDF]
Plasmonic nanolasers (spasers) are of intense interest, attributable to their ability to generate a high-intensity coherent radiation. We infiltrated a three-dimensional silica-based photonic crystal (PhC) film with spasers, composed of spherical gold cores, surrounded by silica shells with dye molecules.
