Coupling of a Laser Diode to a Single-Mode Polarization-Maintaining Fiber
An accurate method for coupling a laser diode(LD)to a single-mode polarization-maintaining fiber was proposed, the beam quality of the semiconductor laser was measured, and its collecting, collimating, forming and coupling into fiber were experimentally investigated.At the meantime, the positioning sensitivities of the shaping system and the fiber were measured.The theoretic analysis of spherical surface lenticule optical fiber and laser diode coupling was made.The lens parameters, the coupling form and the influence of laser diode wave scattering on the coupling efficiency and characteristics were discussed.The computed results and experi-mental data of two practical coupling systems were given and compared to the theoretic calculated results.Fine-ly, the optimal parameter of the lenticule was obtained in combination with the experiment.
