摘要： The present invention concerns a method for constructing a light coupling system wherein a grating is manufactured on the surface of a multimode waveguide and defines the entrance of the waveguide for an incident light beam, said grating comprising a repetition of patterns. The grating is defined by a set of parameters comprising: •grating period (P), separating two adjacent patterns, •grating depth (d) between the highest and the lowest point of the pattern, •incident angle mean value (θ) of the incident light with respect to the waveguide. The method comprises a step of optimization of the set of parameters to obtain an optimized second set of parameters, in order to obtain a transmission efficiency (Ce) of the incident light into said waveguide for the first or the second diffractive order exceeding 35% for unpolarized light, or exceeding 50% for polarized light, at a given wavelength of the incident light.

摘要： The present invention discloses an optical fibre (20) for coupling to an optical source (18) which includes a core (22) and a tip portion (36). The core (22) is for receiving light directed from the optical source along an optical axis; wherein the core is expanded near one end of the optical fibre, and the expanded core (24) having a diameter larger than other portions of the core that are not expanded. The tip portion (36) is on the end of the optical fibre, wherein the tip portion further includes an endmost face (26), the endmost face being non-perpendicular to the optical axis. A coupling system including such an optical fibre and a method of fabricating a coupling device for the optical fibre are also disclosed. The optical fibre as provided by the present invention not only enables high coupling efficiency with different laser mode sizes, but also reduces the back reflected laser from the optical fibre which may otherwise damage the laser semiconductor chip.
