Title:
SEMICONDUCTOR STRIP LASER AND SEMICONDUCTOR COMPONENT
Document Type and Number:
WIPO Patent Application WO/2015/154975
Kind Code:
A3
Abstract:
The invention relates to a semiconductor strip laser which, in at least one embodiment, comprises a first semiconductor region (11) of a first conductivity type. Furthermore, the semiconductor strip laser includes a second semiconductor region (13) of a second conductivity type. An active zone (12) for generating laser radiation is located between the semiconductor regions (11, 13). A strip waveguide (3) is formed in the second semiconductor region (13). The strip waveguide (3) is set up for one-dimensional wave guidance along a waveguide direction (L). A first electric contact (41) is located on the first semiconductor region (11), and a second electric contact (43) is located on the second semiconductor region (13). Furthermore, the semiconductor strip laser (1) includes a heat spreader (2) which, at least up to a temperature of 220° C, is dimensionally stably connected to the semiconductor regions (11, 13). The heat spreader (2) has an average thermal conductivity of at least 50 W/mK.
