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.
