  • Passive compensating coupling laser device
    Patent number: 7054527
    Abstract: In an optical or optoelectronic module (1) an intermediate medium (4, 10) whose optical index decreases with temperature is introduced into the optical path (7) between a laser diode (9) and an optical fiber (5). This compensates, by passive means, the power losses of the laser emission due to the increase in operating temperature by improving the transmission between the diode (9) and the fiber (5). The intermediate medium (4, 10) is preferably deposited in the form of a capsule (10) enveloping the diode (9) and the end of the fiber (5). This achieves, by passive means, a transmitted power that is independent of the operating temperature.
