A detailed numerical analysis of mid infrared quantum cascade lasers (QCLs) is carried out by solving the standard two-level rate equations. This analysis accounts for the influence of optical mode confinement factor (Γ), spontaneous emission factor (β) and Reflectivities (R) of the facets on the dynamics of the mid-infrared QCL. The dependence of threshold current, Steady state photon number, electron number in different levels, built-up time on the device parameters is investigated thoroughly. This analysis aids in determining optimum values of device parameters and operating conditions..

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.
