Optical gain in monodispersed silicon nanocrystals

Under high power pulsed excitation,positive optical gain can be observed once a good optical confinement in the waveguide is achieved and the silicon nanocrystals have proper size.A critical tradeoff between Auger nonradiative recombination processes and stimulated emission is observed.Optical gain and stimulated emission in silicon nanocrystalsTime-resolved luminescence measurements on silicon nanocrystal waveguides have revealed a fast recombination dynamics,related to population inversion which leads to net optical gain.The waveguide samples were obtained by thermal annealing of plasma enhanced chemical vapour deposited thin layers of silicon rich oxide Variable stripe length measurements performed on the fast emission signal Optical gain and stimulated emission in nanocrystal We examined the competing dynamical processes involved in optical amplification and lasing in nanocrystal quantum dots and found that,despite a highly efficient intrinsic nonradiative Auger recombination,large optical gain can be developed at the wavelength of the emitting transition for close-packed solids of these dots.
