Author Affiliations +
This paper proposes an optical continuous-phase frequency shift keying (CPFSK) modulation scheme with an arbitrary modulation index. Simulations on the performances of CPFSK and differential phase shift keying (DPSK) show that CPFSK of modulation index is 2/3 performs best on receiver sensitivity, dispersion penalty and nonlinearity in the balanced receiving system of 40G.
