Several biological membranes have been served as scattering materials of random lasers, but few of them include natural photonic crystals. Here, we propose and demonstrate a facile approach to fabricating high-performance biological photonic crystal random lasers, which is cost-effective and reproducible for mass production. As a benchmark, optical and lasing properties of dye-coated Lepidoptera wings, including Papilio ulysses butterfly and Chrysiridia rhipheus moth, are characterized and show a stable laser emission with a superior threshold of 0.016 mJ/cm², as compared to previous studies. To deploy the proposed devices in practical implementation, we have applied the as-fabricated biological devices to bright speckle-free imaging applications, which is a more sustainable and more accessible imaging strategy.

来自蝴蝶和飞蛾光子晶体翅膀的随机激光用于无斑点成像

几种生物膜已被用作随机激光的散射材料，但其中很少包括天然光子晶体。在这里，我们提出并展示了一种制造高性能生物光子晶体随机激光器的简便方法，该方法具有成本效益且可重复用于大规模生产。作为基准，染料涂层鳞翅目翅膀（包括Papilio ulysses蝴蝶和Chrysiridia rhipheus蛾）的光学和激光特性被表征，并显示出稳定的激光发射，具有 0.016 mJ/cm ²的优越阈值，与以前的研究相比。为了在实际实施中部署所提出的设备，我们已将制造的生物设备应用于明亮的无斑点成像应用，这是一种更可持续且更易于访问的成像策略。
