Femtosecond pulse propagation in a cadmium sulfide semiconductor quantum dot waveguide

Abstract

Most of the researches on the nonlinear optics of semiconductors have been focused on quantum wells and devices associated with them.1 In quantum dots, the carrier motion is restricted in all three dimensions, leading to interesting new device concepts. The presence of quantum confined transitions in the dots leads to narrowing of the optical spectra (gain and absorption), making them potentially attractive for the development of superior devices. The recent development in the ion- exchanged waveguide fabrication in glass2 makes it possible to build quantum dot slab and channel waveguide devices. We have succeeded in fabricating the first channel waveguides in cadmium sulfide (CdS) quantum dots in borosilicate glass samples, made by the sol-gel technique.3 We have studied the femtosecond laser pulse propagation through these waveguides and have seen very interesting pulse breakup effects for pulses whose center frequency is detuned well below the lowest quantum confined transition.
