Ultralow Threshold Silicon Based all Optical Dielectric NanoLaser

An all- optical dielectric laser composed of a silicon bowtie nanoantenna placed on a silicon photonic crystal nano cavity is introduced in this paper. The designed optically pumped laser which resonates within a relatively broad range of wavelengths strongly enhances the incident light at the wavelengths of λ = 1.55µm.
