Influence of using two oxide layers in the both sides of active layer with different position and aperture size on Vertical Cavity Surface Emitting Laser (VCSEL) performance is analyzed showing effects on the output power, single mode operation and threshold current. In addition, for improving speed we use ion implant area along with thick oxide layer to minimize parasitic elements. As the result, the proposed design exhibits much better stability of the fundamental mode over a wider current range, much higher output power, lower threshold current, than the conventional one with a high frequency response.
