Abstract: A light source includes a first waveguide. The first waveguide includes a light emitting material having a first index of refraction and at least one layer is disposed over the light emitting material. The at least one layer has a second index of refraction and the first index of refraction is greater than the second index of refraction. The light source also includes a second waveguide, which is coupled to the first waveguide. The light emitting device also includes a light extraction structure.

Abstract: An optical waveguide environmental sensor is provided that is capable of detecting a target gas or liquid in the ambient environment in an advantageously short period of time. The waveguide is preferably in the form of an optical fiber having a cladding that contains a photonic band gap structure which in turn envelopes a light conducting, hollow core portion. The cladding further includes at least one elongated side opening that preferably extends the entire length of the fiber and exposes said hollow core portion to the ambient environment, which provides broad and nearly immediate access of the core portion to gases and liquids in the ambient environment, thereby minimizing sensor response time. The ambient gases or liquids filling the hollow core portion and elongated opening function as a ridge and slab, respectively, of an optical ridge waveguide that effectively supports at least one bound optical mode.

Abstract: A microstructured optical fiber (30) is described. The microstructured optical fiber (30) comprises an inner region (32) and an outer region (34). The inner region (32) includes an inner material (36) and a plurality of holes formed in the inner material (36). The outer region (34) surrounds the inner region (32), and includes an outer material (42). The softening point temperature of the inner material (36) is greater than the softening point temperature of the outer material (42) by at least about 50 °C. Microstructured optical fiber preforms and methods for making the microstructured optical fibers are also described. The microstructured optical fiber may be made to have substantially undistorted holes in the inner region.
