Abstract
This paper presents a novel method to tune the optical buffers center frequency, bandwidth and slow down factor. In this way, we consider the diamagnetic shift of exciton energy levels in quantum wells. Analysis and simulation of a basic GaAs/AlGaAs quantum wells optical buffer verifies the ability of this new method to control the frequency and time domain properties of an optical slow light device. Simulation shows that magnetic field intensity could increase the limited gigahertz bandwidth of this device up to 1 THz. These achievements are useful in optical nonlinearity enhancement and all-optical signal processing applications.
