摘　　要：A 1.60μm laser diode and electroabsorption modulator monolithically integrated with a novel dual-waveguide spot-size converter output for low-loss coupling to a cleaved single-mode optical fiber are demonstrated.The devices emit in a single transverse and quasi single longitudinal mode with an SMSR of 25.6dB.These devices exhibit a 3dB modulation bandwidth of 15.0GHz,and modulator DC extinction ratios of 16.2dB.The output beam divergence angles of the spot-size converter in the horizontal and vertical directions are as small as 7.3°×18.0°,respectively,resulting in a 3.0dB coupling loss with a cleaved single-mode optical fiber.报道了1.6μm的半导体激光器和电吸收调制器以及双波导模斑转换器的单片集成器件.该器件具有良好的单横模特性和准单纵模特性(边模抑制比达25.6dB),3dB调制带宽为15GHz,直流消光比为16.2dB,远场发散角为7.3°×18.0°,和单模光纤的耦合效率达3.0dB.
