An ultrafast all-optical AND gate at 1.55 μm based on low-temperature-grown Be-doped strained InGaAs/InAlAs multi-quantum wells is developed. The device has femtosecond response time, very large contrast ratio, and wide operational wavelength range as well as polarization insensitivity. The values obtained are deemed to be the highest among all the semiconductor-based all-optical AND gates reported to date.
