Problems solved by technology
While metallic waveguides have a long history of use at longer wavelengths (e.g. microwaves), their use as waveguides in the optical wave range (e.g. 350 nm to 3 microns) has been limited by their absorption properties

Embodiment Construction
[0149] The present invention relates to fiber waveguides having co-drawable sections comprising different optical materials. These portions are the structural elements of the fiber waveguide that determine the optical properties of the waveguide (eg, the structural elements that determine how the waveguide confines an optical signal to one path). One such fiber waveguide is a conventional optical fiber (hereinafter referred to as "optical fiber") in which the sections include a core and an outer cladding section surrounding the core. The core and outer cladding cause optical energy in a subset of frequencies to propagate along the waveguide axis while being confined to the core. Another example of a fiber waveguide is a photonic crystal fiber, which includes a core and a confinement region. The confinement region has a change in refractive index that creates a band gap and reflects light in a range of frequencies, confining it to the core. One type of photonic crystal fiber ...

Abstract
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.
