摘要	Coupling system between an optical waveguide (1) and an optical device (8) suitable for receiving and/or transmitting an optical beam having a first maximum MFR, comprising a single-mode optical fiber (1) having at one end a portion (10) of its core (2) expanded with a second MFR. An aspherical lens (6) is formed on said end of the fiber (1). Said aspherical lens comprises a pair of inclined surfaces (41, 42) which intersect on a line, generating an edge, in a position substantially corresponding to the center of said core (2), said edge is rounded to form an aspherical profile.
其他摘要	光波导（1）和光学装置（8）之间的耦合系统，适用于接收和/或发射具有第一最大MFR的光束，包括单模光纤（1），其一端具有一部分（10）其核心（2）扩展了第二个MFR。在光纤（1）的所述端部上形成非球面透镜（6）。所述非球面透镜包括一对倾斜表面（41,42），所述倾斜表面在一条线上交叉，产生边缘，在基本上对应于所述芯（2）的中心的位置，所述边缘被倒圆以形成非球面轮廓。
主权项	Laser emission system comprising a laser (100) suitable for transmitting an elliptical optical beam at an emission wavelength less than 1000 nm, having a first maximum MFR, comprising a flared optical waveguide (105), a single-mode optical fibre (1) at said emission wavelength, having a terminal portion with a second MFR, characterized in that said MFR of said fibre does not differ from said first maximum MFR of the laser (100) by more than 20%.
