The propagation of ultrashort optical pulses in semiconductor-doped glass waveguides is investigated theoretically for wavelengths below the half bandgap. The linear and non-linear properties of the composites are obtained and a field equation for pulse propagation is derived. This equation yields a new family of sub-picosecond optical solitons which are observed in numerical simulations. Interesting applications are anticipated for ultrafast all-optical signal processing.
