Semiconductor quantum dots are being investigated as a new material system for a variety of optoelectronic applications. We will discuss applications of quantum dots for optical switching in waveguide structures, optical data storage, and potential light sources. We emphasize why quantum dots with discrete spectra are expected to be superior in many applications compared with other systems, such as bulk and quantum wells with continuum spectra. We also report on our fabrication of cadmium sulfide quantum dot sol-gel glass channel waveguides using the potassium ion-exchange technique. The waveguides were optically characterized and cross-correlation measurements showed significant pulse shaping, both spectrally and temporally, after femtosecond laser pulses were propagated through the waveguide.
