Abstract: Electrical pumping of photonic crystal (PC) nanocavities using a lateral p-i-n junction is described. Ion implantation doping can be used to form the junction, which under forward bias pumps a gallium arsenide photonic crystal nanocavity with indium arsenide quantum dots. Efficient cavity-coupled electroluminescence is demonstrated in a first experimental device. Electrically pumped lasing is demonstrated in a second experimental device. High speed modulation of a single mode LED is demonstrated in a third experimental device. This approach provides several significant advantages. Ease of fabrication is improved because difficult timed etch steps are not required. Any kind of PC design can be employed. Current flow can be lithographically controlled to focus current flow to the active region of the device, thereby improving efficiency, reducing resistance, improving speed, and reducing threshold.
