Abstract :
An optical frequency-shift-keying (FSK) modulator with a pair of Mach-Zehnder structures that can switch optical frequency is developed. The operation is demonstrated at a 10 Gbit/s FSK transmission conducted on a standard single-mode fibre of 60 km, where the FSK signal is demodulated by a fibre Bragg grating.
