A unique photonic crystal fiber (PCF) which consists of circular core surrounded by square lattice cladding is presented. The square lattice cladding further consists of square-shaped air holes. Flattened chromatic dispersion (D) is obtained for this structure in the C and L communication bands at different values of the ratio of square hole width to the pitch (d/Λ) of the PCF. The main advantage of this structure is its high dispersion tolerance capability for change in the distance between core and square holes cladding (d1). There is observed only about 2.4 ps/nm-km variation in D for -5 to +5% change in d1. Effective mode area has been obtained for this PCF structure which comes out to be small enough to make this fiber suitable to be used in non-linearity related applications..

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.
