摘要:
A mirror structure includes a plurality of features of a defined size. The features include alternating spatial units of a chalcogenide glass and a thermoplastic polymer, and are specifically arranged in an ordered form so that the structure is highly reflective. Thermally-assisted methods are introduced for forming such structures.

In general, in one aspect, the invention features systems, including a photonic crystal fiber including a core extending along a waveguide axis and a dielectric confinement region surrounding the core, the dielectric confinement region being configured to guide radiation along the waveguide axis from an input end to an output end of the photonic crystal fiber. The systems also includes a handpiece attached to the photonic crystal fiber, wherein the handpiece allows an operator to control the orientation of the output end to direct the radiation to a target location of a patient.
