Experimental demonstration of a multifunctional long-wavelength vertical-cavity laser amplifier-detector

Vertical-cavity optical AND gate

“…Vertical-cavity semiconductor optical amplifiers (VCSOAs) are drawing increasing research attention in the past few years [7,8]. As compared with in-plane SOAs, VCSOAs exhibit several advantages including higher coupling efficiency and lower noise figure, due to their circular geometry and small dimensions.…”

Optical bistability in a Vertical-Cavity Semiconductor Optical Amplifier (VCSOA): pulsed input

“…With in-plane devices, the possibility of the large-scale integration is limited. In the past few years, VCSOAs have drawn increasing research attention [7,8]. As compared to in-plane SOAs, they exhibit several advantages including higher coupling efficiency to optical fibers and lower noise figure due to their circular geometry and small dimensions, respectively.…”

1.3 μm vertical cavity amplifier

“…Recently, electrical pumping of a reflection type VCA at 1.5 m has demonstrated 18-dB continuous wave (CW) gain, a gain-bandwidth product of 25 GHz, and a saturation output power of 25 dBm at 218K [2]. In this work we demonstrate the first CW amplification at 1.3 m for a VCA.…”
