摘要:
A dynamic single-mode laser transmitter which is formed with a multi-mode semiconductor laser (1) and an external resonator in the form of a mirror (21) mounted adjacent an exit face (12) of the laser (1) which emits laser light (20) which can be manufactured in a simple manner and is compact and particularly temperature stable and wherein the mirror (21) is formed on the end face (22) of a metal member (2) which is fixed to a common carrier member (3) that also carries the semiconductor laser (1). The laser transmitter of the invention can be used in optical communication and in broadband systems for example.
摘要:
With a light waveguide feedthrough for optoelectronic modules a light waveguide fiber (1) is guided hermetically tight and mechanically stable, in particular long-term stable, directly through a module housing wall. The light waveguide fiber (1) is compression glazed in the housing-side front portion of a relatively thick-walled metal tubule (2) without external coating (5) and affixed by adhesion in its rear portion. An application of the light waveguide feedthrough according to the invention is in optoelectronic transducer modules.
