This article describes recent research activities using an NICT novel optical device, the optical frequency-shift-keying (FSK) modulator, which can provide high-speed control of optical frequency, phase and amplitude. The FSK modulator can generate various types of high-speed optical signals, precisely. We show a couple of examples of recent results on applications of the FSK modulator for next-generation optical communications systems, such as, optical FSK label processing, tunable optical buffer techniques, high-speed differential quadrature-phase-shift-keying (DQPSK) signal generation for 100 GbE and continuous-phase FSK signal generation for dense wavelength-domain-multiplexing.
