—Recently, we have introduced a numerical method for calculating local dispersion of arbitrary shaped optical waveguides, which is based on the Finite-Difference Time-domain and filter diagonalization technique. In this paper we present a study of 40 Dastmalchi et al. photonic crystal waveguides at interfaces and double hetero-structure waveguides. We have(More)
This study aimed to investigate the relationship between empowerment and organizational The study was a type of correlation studies and has been implemented as field study in spring 2012. The population included all employees of Guilan University and Islamic Azad University, Rasht branch staffs (N=973) that by simple randomly method and using Morgan and(More)
We consider a broad area vertical-cavity driven semiconductor laser (VCSEL) that includes the multiple quantum well structures. The semiconductor microresonator is of the Fabry-Perot type that provides the longitudinal single mode operation. The dynamical behavior of these nonlinear systems is described by Maxwell-Bloch equations. The standard adiabatic(More)
