  • Semiconductor laser comprising a plurality of optically active regions
    Publication number: 20040120377
    Abstract: There is disclosed an improved semiconductor laser device (10), and particularly, a broad area semiconductor laser with a singe-lobed far field pattern. Known broad area lasers are used for high power applications, but suffer from a number of problems such as filamentation, instabilities in the transverse mode, and poor far-field characteristics. The present invention addresses such by providing a semiconductor laser device (10) comprising: a plurality of optically active regions (240); each optically active region (240) including a Quantum Well (QW) structure (77); adjacent optically active regions (24) being spaced by an optically passive region; the/each optically passive region (245) being Quantum Well Intermixed (QW). The spacing between adjacent optically active regions (240) may conveniently be termed “segmentation”.
