Abstract

Semiconductor lasers with ring cavities are attractive as possible sources for future fibreto-the-home systems that require affordable components. Ring resonator lasers can readily be integrated and do not require gratings or facets for feedback. They can be operated cw [1] in a single transverse and longitudinal mode [2] without the need for accurate gratings or overgrowth and hence offer themselves strongly for low-cost mass-production.
