Abstract
Modulation instability (MI) in passively mode-locked dissipative
solitons lasers has been studied. The factors that affect MI, including the
intensity of the nonlinear wave and the linear phase delay of the cavity,
have been experimentally studied. It's found that MI induces sidebands in
the spectrum of dissipative solitons. The sidebands can cause the pedestal
on the pulse in time domain and thus limit the pulse duration. Additionally,
a simple method to eliminate the sidebands is proposed and nearly pedestal
free pulses are generated correspondingly. Finally, based on MI, a method
to measure the cavity net dispersion is proposed and applied to two dissipative
soliton lasers with different net dispersion. It's shown that the positions
of the adjacent spectral sidebands can determine the intracavity net dispersion,
and the measurement error is limited by the accuracy of the optical spectrum
analyzer. This indicates it is a simple and precise method to measure the
intracavity net dispersion.
