Abstract

We reported an optical amplification of electrically driven dilute nitride 1.3 m vertical cavity semiconductor optical amplifier (VCSOAs) with 5 m aperture at room temperature. With the help of amplified spontaneous emission and amplified optical signal, gain is calculated with respect to injected light's wavelength and power for two types of samples, which are with and without a confinement layer located at the top of bottom Distributed Bragg Reflector (DBR). At lower injected laser powers, nearly 10 dB gains are observed for both samples. At power injections over 1nW, gain is observed to drop to a value of 0 dB, drastically. For nearly all power values, sample with confinement layer represents slightly higher gain.
