Numerical analysis of flared semiconductor laser amplifiers

Abstract

A numerical model for flared semiconductor optical amplifiers that incorporates the effects of gain and index saturation and thermal effects is presented. Theoretical near fields, far fields, and quadratically phase-corrected far fields are presented. The results indicate that flared semiconductor laser amplifiers are capable of coherent diffraction-limited output powers in excess of 1 W CW.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
