摘要：

In this presentation we will present a new passive alignment method used to obtain highly efficient optical fibre coupling from VCSELs (vertical-cavity surface-emitting lasers). This method is compatible with low-cost, high-yield volume production of compact transceivers for applications in rugged environments. Coupling efficiencies larger than 94% have been obtained using this visually-aided passive alignment method for the coupling between a rounded-tip, 50 mu m core graded-index fibre and an 850nm VCSEL having an emission area diameter of approximately 25 mu m. Our alignment procedure was used to make compact, high-speed (2Gbps) transceivers that can work from -50 to 105 degrees C. They have shown to be able to resist to mechanical shocks of more than 200g. They have also shown to maintain a constant coupling efficiency while being submitted to 35Grms random vibration tests around 200Hz.
