This invention relates to devices for coupling light (90) between an optical waveguide (91, 95) and an optical element in a manner that is substantially independent of temperature, using reflective optics (93, 96). Preferred embodiments incorporate parabolic, quasi-parabolic, elliptical or quasi- elliptical reflectors (93, 96). The transmit and receive elements and associated waveguides (91, 95) preferably comprise photo-patternable polymers.

L'invention ci-décrite concerne des dispositifs servant à coupler la lumière (90) entre un guide d'ondes optique (91, 95) et un élément optique selon une manière qui est sensiblement indépendante de la température et qui fait intervenir l'optique réflexive (93, 96). Parmi les modes de réalisation préférés, figurent les réflecteurs paraboliques, quasi-paraboliques, elliptiques ou quasi-elliptiques (93, 96). Les éléments d'émission et de réception ainsi que les guides d'onde associés (91, 95) comportent de préférence des polymères se prêtant à la photo-formation des motifs.
