We measured optical modal gain of a dye-virus hybrid structure using a variable stripe length method, where Alexa-fluor-488 dye was coated on a virus assembly of M13 bacteriophage. Inspired by the structural periodicity of the wrinkle-like virus assembly, the edge emission of amplified spontaneous emission was measured for increasing excited optical stripe length, which was aligned to be either parallel or perpendicular to the wrinkle alignment. We found that the edge emission showed a strong optical anisotropy, and a spectral etalon also appeared in the gain spectrum. These results can be attributed to the corrugated structure, which causes a similar effect to a DFB laser, and we also estimated effective cavity lengths.
我们使用可变条纹长度方法测量了染料-病毒混合结构的光学模式增益，其中Alexa-fluor-488染料被包覆在M13噬菌体的病毒聚集体上。受皱纹状病毒聚集体结构周期性的启发，测量了放大自发辐射的边缘发射随激发光条纹长度增加的变化情况，激发光条纹长度与皱纹排列方向平行或垂直。我们发现边缘发射表现出强烈的光学各向异性，并且在增益谱中还出现了光谱标准具。这些结果可归因于波纹结构，它对分布反馈激光器产生了类似的效应，我们还估算了有效腔长。
