英文摘要 | An optical coupling system and optical module having a light emitting device for emitting light having different beam spread angles in vertical and horizontal directions. The optical coupling system and module include a first lens for changing the emitted light into parallel rays, a beam shaping and aberration correction device for expanding or contracting a beam cross section of the parallel rays only in a horizontal or vertical direction and for correcting for aberration. Further, a second lens is provided for converging the shaped aberration corrected beam onto an optical fiber for receiving the converged light with an improved coupling efficiency. The aberration correction corrects for astigmatism. |
