Determination of Erbium Distribution in Optical Fibers Using Confocal Optical Microscopy
Uttamchandani, D.; Othonos, Andreas S.; Hubert, M. (1994)Confocal fluorescence microscopy has been used to detect the 565 nm wavelength fluorescence generated from Er+3 ions present in erbium doped optical fibers, thereby enabling the concentration profile of these ions in the ...

Phase shifted Bragg gratings formed in optical fibres by post-fabrication thermal processing
Uttamchandani, D.; Othonos, Andreas S. (1996)Fibre Bragg gratings have been post-fabrication processed using localised heat treatment, with significant changes to their transmission and reflection characteristics being observed. Experimental results of the spectral ...

Raman spectroscopy using a fiber optic probe with subwavelength aperture
Tsai, D. P.; Othonos, Andreas S.; Moskovits, M.; Uttamchandani, D. (1994)Raman spectroscopy with subwavelength spatial resolution of a diamond sample was recorded using a tapered fiber optical probe in conjunction with a conventional Raman spectrometer. The experiment demonstrates the potential ...
