摘要

A novel high-tolerance coupling configuration of distributed feedback (DFB) lasers to silicon photonic chips based on the dual-lens is discussed in this paper. The coupling efficiency and alignment tolerance of three different coupling schemes were compared and analyzed theoretically. And the simulation was verified experimentally by the laser-to-chip coupling scheme based on the commercial dual-lens. The 1 dB lateral offset tolerances of simulation and experiment are 3 μm and 2.7 μm, respectively.
