Abstract: Hybrid silicon lasers and amplifiers having resonator cavities within a silicon substrate and a two-dimensional material film on the substrate as an optical gain medium are described. The two-dimensional material film may be formed of one or more atomic layers of phosphorene (BP). The number of phosphorene layers may be adjusted to tune the emission wavelength of the hybrid devices.
