The ability to tune the wavelength of light emission on a silicon chip is important for scalable photonic networks, distributed photonic sensor networks, and next generation computer architectures. Here we demonstrate light emission in a chip-scale optomechanical device, with wide tunablity provided by a combination of radiation pressure and photothermal effects. To achieve this, we develop an optically active double-disk optomechanical system through implantation of erbium ions. We observe frequency tuning of photoluminescence in the telecommunications band with a wavelength range of 520 pm, green up-conversion lasing with a threshold of 340±70 μW, and optomechanical self-pulsing caused by the interplay of radiation pressure and thermal effects. These results provide a path towards widely tunable micron-scale lasers for photonic networks.
