We analyze tens‐of‐gigahertz pulse signal generation using a sideband injection‐locking scheme. The numerical model for semiconductor lasers under the external optical injection is based on Lang's equation and has been extended in order to take into account the simultaneous injection of the multiple sidebands of the current‐modulated laser. The numerical‐simulation results show that the unselected sidebands will affect the optical and RF‐spectral characteristics, even though the semiconductor laser is locked to the target sidebands. The simulation results are confirmed by the experimental results. © 2005 Wiley Periodicals, Inc.
