Nanopores are a new class of low dimensional semiconductor nanostructures which have been recently proposed for use
in lasers and other photonic applications. This paper provides an overview of patterned nanopore lattices with an
emphasis on their electronic and optical properties. The ability to control nanopore properties by geometry and material
composition are demonstrated. Two methods for controlled nanopore fabrication are presented and compared. Spectral
characteristics of nanopore lasers are presented. Finite element numerical simulations are also performed to determine
the band structure and emission properties of nanopores.
The Surface Relief Fiber Bragg Grating (SR-FBG) is a viable alternative to the thermocouple for high temperature measurements in industry. To fabricate the SR-FBG we etch a grating into the flat surface of an elliptical-core D-fiber. At high temperature (1000 °C) the optical fiber becomes brittle. To overcome brittleness we thread the fiber through a preheated 0.020 inch diameter stainless steel tube. We insert the small tube into a larger one with a diameter of 0.125 inches. The smaller tube rests on ceramic inserts to prevent contact with the large tube. The end of the D-fiber is fitted with a standard fiber optic connecter. With this packaging scheme we conduct a series of test at high temperature. The sensor is robust with no power loss or Bragg wavelength shift, even after heating for 24 consecutive hours.
