DISTRIBUTED-FEEDBACK LASER HAVING ENHANCED MODE SELECTIVITY Abstract A distributed-feedback laser includes in its grating a localized phase-slip discontinuity which is placed off-center. Such discontinuity results in a quarter-wave phase slip, and it can be placed, e.g., such as to maximize the difference between threshold gain of the lowest-lasing mode and cavity loss of the next-to-lowest-lasing mode. The invention is applicable especially where laser output intensity differs at two output facets and results in enhanced modeselectivity during laser operation.
