A coupling technique between a cone endface fiber and LD with the advantage of high efficiency and low reflectance is presented. The coupling efficiency nearly 90% and the reflectance loss approximately 60 dB are calculated using mode coupling theory. Experimentally, the best coupling efficiency measured is 73.9% and the reflectivity is less than -50 dB. In addition, a new equipment for fabricating the conical microlens is designed, which has the advantages of low cost, simple manipulation, and high finished-product-rate.
