Optical injection locking has been demonstrated as an effective filter for optical communications. These optical filters have advantages over conventional passive filters, as they can be used on active material, allowing them to be monolithically integrated onto an optical circuit. We present an experimental and theoretical study of the optical suppression in injection locked Fabry–Pérot and slotted Fabry–Pérot lasers. We consider both single frequency and optical comb injection. Our model is then used to demonstrate that improving the Q factor of devices increases the suppression obtained when injecting optical combs. We show that increasing the Q factor while fixing the device pump rate relative to threshold causes the locking range of these demultiplexers to asymptotically approach a constant value.

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.
