چکیده
Abstract In this work, a series of silica glass photonic crystal fibers (PCFs) were designed through implementation numerical method [1] based on an experimental model that allows the calculation chromatic dispersion from two structural parameters PCFs. Then, PCFs fabricated by stretching structured preform using calculated preliminary design. Some characterization techniques implemented with aim to find PCF and optical properties. Finally, developed used for supercontinuum generation.

High brightness single mode source of correlated photon pairs using a photonic crystal fiber.
We demonstrate a picosecond source of correlated photon pairs using a micro-structured fibre with zero dispersion around 715 nm wavelength. The fibre is pumped in the normal dispersion regime at ~708 nm and phase matching is satisfied for widely spaced parametric wavelengths. Here we generate up to 10;7 photon pairs per second in the fibre at wavelengths of 587 nm and 897 nm, while on collectin...

Modal cutoff is investigated experimentally in a series of high-quality nonlinear photonic crystal fibers. We demonstrate a suitable measurement technique with which to determine the cutoff wavelength and verify the technique by inspecting the near field of the modes that may be excited below and above the cutoff. We observe a double-peak structure in the cutoff spectra, which is attributed to ...
متن کاملDesign and fabrication of photonic crystal thin film photovoltaic cells
We present the integration of an absorbing planar photonic crystal within a thin film photovoltaic cell. The devices are based on a stack including a hydrogenated amorphous silicon P-i-N junction surrounded by TCO layers, with a back metallic contact. Optical simulations exhibit a significant increase of the integrated absorption in the 300-720nm wavelength range. The global electro-optical cha...
