High Power, High-Order Random Raman Fiber Laser Based on Tapered Fiber

IEEE Photonics Journal, 2017
In this paper, we demonstrate a high power and high-order random Raman fiber laser based on a 1 km novel tapered fiber (TF). The core diameter of the TF gradually increases from 8 μm to 20  μm.

Structure Formation in Butterfly Scales: Interplay of Genetic Control, Mechanical Instabilities, and Dynamic Material Properties

Advanced Functional Materials, EarlyView.
Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.
