R. Goto et al., MUTUAL INJECTION LOCKING BETWEEN 2 DFB LDS WHICH LASE AT FREQUENCIES SEPARATED BY ONE FABRY-PEROT MODE SPACING, Electronics Letters, 34(17), 1998, pp. 1669-1670
A new type of mutual injection locking between two distributed Feedbac
k laser diodes (DFB LDs) of the same structure is proposed and experim
entally confirmed. The lasing frequencies and the spectra are locked a
nd stabilised when the lasing frequency difference of the two LDs was
equal to one Fabry-Perot mode spacing.
