Dispersion properties of Hollow-core PCF or micro-structured PCFs are investigated via Finite Element Method (FEM). FEM is attractive simulation technique as it can handle complicated structure geometries very effectively. In this paper, the dispersion characteristics, mode effective refractive index, non-linear co-efficient and effective mode area of 3-ring hexagonal hollow-core PCFs have been investigated by using FEM. By suitable designing of 3-ring air holes of hollow-core photonic crystal fiber at operating wavelength from 0.65μm to 1.55μm nice modal field patterns of guided light were found. The core diameter, pitch and air hole diameter of 3-ring PCF designed in our investigation are 0.2 μm, 2.3 μm and 1.38 μm respectively. A nearly zero dispersion of the newly designed PCF is then observed at wavelength 0.98 μm.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
