我们描述了一种新型的集成有机-无机波导/光电探测器，其内部量子效率为（53/spl + usmn/15%）。通过有机分子束沉积（OMBD），在预处理的InGaAs光电探测器上直接生长低损耗（10-/spl mu/m宽波导2.7/spl plusmn/0.3 dB/cm at /spl lambda/=1.064 /spl mu/m）的晶体有机波导，而不影响光电二极管的暗电流或电容。波导的偏振保持特性表明，在真空沉积过程中，有图案的衬底显著影响有机分子的取向。
We describe a novel, integrated organic-inorganic waveguide/photodetector with an internal quantum efficiency of (53/spl plusmn/15%). Low-loss (2.7/spl plusmn/0.3 dB/cm at /spl lambda/=1.064 /spl mu/m for 10-/spl mu/m wide waveguides) crystalline organic waveguides are grown directly onto the pre-processed InGaAs photodetector by organic molecular beam deposition (OMBD) without affecting either the dark current or capacitance of the photodiode. The polarization-preserving nature of the waveguides suggests that a patterned substrate significantly influences the organic molecular orientation during vacuum deposition.
