Frequency combs obtained by sinusoidal phase modulation of narrow-band continuous-wave lasers are widely
used in the field of optical communications. However, the resulting spectral envelope of the comb is not
at. In
this Letter, we propose a general and eficient approach to achieve
at frequency combs with tunable bandwidth.
The idea is based on a two-step process. First, eficient generation of a train with temporal
at-top-pulse profile
is required. Second, we use large parabolic phase modulation in every train period in order to map the temporal
intensity shape into the spectral domain. In this way, the resulting spectral envelope is at and the size is tunable with the chirping rate. Two diferent schemes are proposed and verified through numerical simulations. [-]
