FIGURE 1. Optical frequency upconversion of femtosecond pulses is performed via intermodal four-wave mixing from a large-mode-area microstructured fiber (left) and via the Cherenkov radiation from a small-mode-area microstructured fiber (right). Vertical arrows represent the pump wavelength; the insets represent the far-field images of the exiting light from the fibers.

SPECIALTY FIBERS: Targeted pulse-energy routing in fiber drives nonsupercontinuum applications

Stephen A. Boppart

July 1, 2009

While routing femtosecond pulse energy to a broadband spectrum in optical fibers is important, many emerging nonsupercontinuum applications require selective routing of the pulse...
