Conventional DFB laser diodes present symmetric emission patterns, thus making these structures inadequate as single‐mode lasers. The simplest way of achieving single longitudinal‐mode operation is to make one or more facets as cleaved, rather than using AR coating. Single‐mode yield in asymmetric structures is calculated using matrix techniques. © 2005 Wiley Periodicals, Inc.
