Abstract :
Injection locking of a GaAlAs laser by coupling into non-lasing Fabry-Perot modes is described. Locking of a slave laser mode as far as 22 mode spacings (60 Ã
) away from the gain curve centre is obtained. The dependence of the locking bandwidth on the injected power and the wavelength separation between the free-running and injected mode (¿¿) is described. The dependence of the power required for locking on the magnitude of ¿¿ is consistent with a 192 Ã
-wide quadratic gain profile.
