Abstract

A new semiconductor laser design, the leaky-guided channeled substrate planar (LCSP) laser is presented. The analysis, by using the effective index method in the complex domain, shows that the LCSP structure provides better lateral mode stability than either gain guided or positive index step structures. The LCSP structure with reduced heating and strong lateral coupling effect may be more useful for high power linear array lasers.
