Optical injection locking of longitudinal modes in a discrete mode laser: application in gain-switched optical frequency combs
A detailed experimental study of the effect of external optical injection (OI) on a single-mode discrete mode laser (DML) when the wavelength of the OI is far from that of the solitary DML is presented. We show that the situation observed in Fabry Pérot lasers by Jain et al. extends to single-mode D...
