Biomimetics: Small 9/2010

The cover image shows a scanning electron microscopy image of bioinspired subwavelength structures (SWS) with parabolic shape, which are fabricated by simple process steps based on the combination of laser interference lithography, thermal reflow, and subsequent pattern transfer. The insets depict the reflected light from the flat surface (top) and parabola-shaped SWS (bottom), respectively. The fabricated SWS with parabolic shape show antireflection properties over a broader wavelength range compared to that of a flat surface and even conventional cone-shaped SWS, thus opening up new possibilities for various optoelectronic device applications to improve optical performance. For more information, please read the Communication “Bioinspired Parabola Subwavelength Structures for Improved Broadband Antireflection” by Y. T. Lee el al., beginning on page 984.
