All optical flip-flop and inverter using adjacent lasing wavelengths emitting from semiconductor microring laser

We demonstrated all optical flip-flop and inverter using two adjacent lasing wavelengths by a semiconductor MQW microring laser. The lasing wavelength (1567.54nm) and both side adjacent lasing wavelengths (1565.84nm and 1569.24nm) were used as the injection light wavelength. These operations were realized in the same device with different control current.
