| 英文摘要 | A VCSEL (Vertical Cavity Surface Emitting Laser) structure (1), wherein at least one cross-section of the VCSEL structure perpendicular to the optical axis (2) of the VCSEL structure comprises a mode selecting shape (10) promoting output of the fundamental transverse mode of the resonator while suppressing output of the higher modes. According to the present invention, the mode selecting shape (10) comprises a longitudinal portion (101) being directed past the optical axis (2) and having a one-sided broadening (102) forming a central area (103) around the optical axis, the geometry of the mode selecting shape being chosen to concentrate the fundamental mode in the central area while guiding the possible higher modes away from the optical axis through the longitudinal portion. |
