摘要：

We consider large-mode-area photonic crystal fibers for visible applications in which microdeformation-induced attenuation becomes a potential problem when the effective area A(eff) is sufficiently large compared to lambda(2). We argue that a slight increase in fiber diameter D can be used in screening the high-frequency components of the microdeformation spectrum mechanically, and we confirm this experimentally for both 15- and 20-mum core fibers. For typical bending radii (R similar to 16 cm) the operating bandwidth increases by approximately 3-400 nm to the low-wavelength side. (C) 2003 Optical Society of America.
