Paper Abstract

Semiconductor CdS quantum dot-doped sodium borosilicate glasses were successfully fabricated by the sol-gel technique. The dot size and concentration of CdS are controlled by chemistry and processing conditions. Optical absorption spectra were measured for these quantum dot-doped glasses, and absorption shoulder due to the exciton effect was observed. Nonlinear optical properties of high third-order susceptibility, (chi) (3), and room-temperature optical gain were observed. Potassium ion exchange was performed on the glass, and channel waveguides were successfully fabricated in the CdS-doped glass. The waveguide was tested with single mode laser pulses, and single mode output was demonstrated. Spectral broadening of the output pulses was observed.
