HIGH INDEX-CONTRAST FIBER WAVEGUIDES AND APPLICATIONS

摘要

The invention features high index-contrast fiber waveguides (1301) that can be drawn from a preform. The invention also features materials for forming high index-contrast fiber waveguides (1301), and guidelines for their selection. High index-contrast fiber waveguides (1301), which may include opical fibers and photonic crystal fibers, can provide enhanced radial confinement of an optical signal in the fiber waveguide (1301). Moreover, large optical energy densities can be achieved inside the high index-contrast fiber waveguides, making them attractive candidates for a number of applications.
