Ultrafast decay of femtosecond laser-induced grating in silicon-quantum-dot-based optical waveguides
Femtosecond transient laser-induced grating (LIG) experiments were performed in planar optical waveguides made of luminescent silicon quantum dots. The LIG was created by interference of two pulses from the frequency-doubled output of a Ti-sapphire laser
