Optical transmission device has an optical fiber coupled by waves evanescent has a waveguide planar

摘要

Optical transmission device (100) comprising at least: - an optical fiber (102) comprising at least one core (104) and a sheath (106) surrounding the core, and having, at the level of at least a portion (110) of the optical fiber, a portion (108) of the core, at least one surface (109) is not covered by the sheath, - a waveguide planar (120, 140) comprising means of coupling by evanescent waves (162) arranged in the vicinity of said surface of the portion of the core of the optical fiber, a straight line perpendicular to said surface, forming, with an axis of revolution (103) of the optical fiber, an angle between φc and 90°, such that: with n: refractive index of the material of the core of the optical fiber, and n the refractive index of a material from which are made of the coupling means.
