Abstract

We have demonstrated, the first time to our knowledge, a low-input intensity high-contrast (10:1) optical AND gate based on the differential gain (optical bistability) observed in an 850 nm GaAs vertical-cavity semiconductor optical amplifier (VCSOA). The input switching power is about 6 μW, which equals to the intensity of 16nW/μm2. It is about 2 orders of magnitude lower than in in-plane semiconductor optical amplifiers. In the experiment the device also shows an optical gain of 10 dB.
