Optically thin palladium films on silicon-based substrates and nanostructure formation: effects of hydrogen
Othonos, Andreas S.; Kalli, Kyriacos; Tsai, D. P. (2000)Optically thin palladium films evaporated on different silicon-based substrates are investigated following exposure to different concentrations of hydrogen gas in air. Laser modulated reflectance off the palladium surface ...

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 ...

Spectrally broadband Bragg grating mirror for an erbium-doped fiber laser
Othonos, Andreas S.; Lee, X.; Tsai, D. P. (1996)The authors design and demonstrate a high-reflector broadband Bragg mirror for a fiber laser system. A T-matrix formalism was used to design a broadband intracore mirror consisting of a series of Bragg gratings. Ultraviolet ...
