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/cm, 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.
已经有几种生物膜被用作随机激光的散射材料，但它们很少包含天然光子晶体。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的简单方法，这种方法具有成本效益，并且可重复用于大规模生产。作为基准，我们对涂有染料的鳞翅目昆虫翅膀（包括 Ulysses 蝴蝶和 Rhodope 蛾）的光学和激光特性进行了表征，并与以前的研究相比，显示出具有稳定激光发射和优越的 0.016 mJ/cm 的阈值。为了将所提出的器件应用于实际实施中，我们将所制造的生物器件应用于无亮斑的清晰成像应用中，这是一种更可持续和更易于实现的成像策略。
