Abstract- In this paper, we use a numerical finite difference method for studying vertical cavity surface emitting lasers (VCSEL) in dynamic operation. The quantum-well active layer is sandwiched between two n-type and p-type Bragg reflectors, which provide optical feedback for lasing. An oxide aperture and index guiding structure are promising properties of VCSEL that results increasing and stable single-mode operation. Time and space behavior of carrier concentration, optical field normalized intensity and gain are investigated. The effect of SHB on VCSEL dynamic parameters is illustrated.
