Abstract :
We propose a high-speed versatile lightwave modulator which can generate on-off-keying, phase-shift-keying and frequency-shift-keying signals. 40 Gbit/s optical FSK modulation was demonstrated by using the modulator consisting of four phase modulators, where frequency deviation was 80 GHz.
