Room Temperature Electrically Pumped Silicon Nano-light Source at Telecommunication Wavelengths

We demonstrate electrically pumped silicon nano-light source at room temperature, having very narrow emission line (<0.5nm) at 1500nm wavelength, by enhancing the electroluminescence (EL) via combination of hydrogen plasma treatment and Purcell effect. The measured output power spectral density is 0.8mW/nm/cm(2), which is highest ever reported value from any silicon light emitter.
