中文摘要	the reduced divergence angle of the photonic crystal vertical-cavity surface-emitting laser (pc-vcsel) was investigated in both theory and experiment. the photonic crystal waveguide possessed the weakly guiding waveguide characteristic, which accounted for the reduction of the divergence angle. the three-dimensional finite-difference time-domain method was used to simulate the designed pc-vcsel, and a calculated divergence angle of 5.2 degrees was obtained. the measured divergence angles of our fabricated pc-vcsel were between 5.1 degrees and 5.5 degrees over the entire drive current range, consistent with the numerical results. this is the lowest divergence angle of the fabricated pc-vcsel ever reported.
