  • 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.

  • Method of aligning an optical component with an inclined guide mounted on a base and the associated optical device
    Publication number: 20020044745
    Abstract: The invention concerns an optical device having an optical component (1) disposed on a base (5) provided with support elements (20), the component having a waveguide (12) and an exit facet (15) situated in a plane perpendicular to the plane of assembly of the component on the base, the said facet being inclined with respect to the plane perpendicular to the axis (11) of the waveguide, an optical wave issuing from the component then propagating in an intermediate medium along an optical exit beam axis (30), characterised in that the optical component has support elements (18) complementary to those (20) of the base and which cooperate with the latter for lateral positioning (x), and in that the complementary support elements (18, 20) are disposed so as not to modify the direction of the said optical axis (30) of the exit beam during a longitudinal movement (z) of the component on the base.
