Surface emitting laser diodes with enhanced higher order spatial modes and/or filamentation |
摘要 |
A surface-emitting laser ("SEL") having predictable filamentation initiation. The SEL includes a light generation layer and first and second mirror layers. The first and second mirror layers reflect light generated in the light generation region back toward the light generation region. Each of the mirrors reflects light such that it adds coherently to the light generated in the light generation region or to the light reflected from the other mirror. One of the mirrors includes a localized imperfection which causes light interacting therewith to be attenuated or shifted in phase relative to light that does not interact with the imperfection region. As a result, lasing filaments are preferentially initiated in the regions adjacent to the localized imperfection.
