Abstract
An interferometric semiconductor laser (YL) as well as optoelectronic arrangements with such a laser are disclosed. The laser has a special coupling segment (Z) which allows high optical output to be obtained without affecting the filtering function or significantly restricting the tuning range of the laser. Such a laser can be coupled with low loss to a subsequent optoelectronic component (e.g., a wavelength converter (WK)) which is monolithically integrated with the laser.
