MOUNTING OF OPTICAL DEVICE ON HEAT SINK

摘要

There is disclosed an improved optical device (10; 10a), eg comprising a semiconductor optically active or optoelectronic devices such as lasers, modulators, amplifiers, switching structures, or the like, mounted on a heatsink (28; 28a). The invention provides an optically active device (10; 10a) comprising a device body (12; 12a) having an active region (14; 14a) and an optically passive region(s) (20; 22) provided at one or more ends (24, 26; 26a) of the active region (14; 14a); and a heatsink (28; 28a); the device body (12; 12a) and heatsink (28; 28a) being retained in thermal association with one another such that a first end of the at least one of the optically passive region(s) (20, 22; 22a) adjacent an end of the active region (14; 14a) is provided within an area of the heatsink (28; 28a), and a second end of the said at least one optically passive region(s) (20, 22; 22a) is provided outwith the area of the heatsink (28; 28a).
