Abstract
A laser structure includes a substrate, a buffer layer formed on the substrate and a light emitting diode (LED) formed on the buffer layer. A photonic crystal layer is formed on the LED. A monolayer semiconductor nanocavity laser is formed on the photonic crystal layer for receiving light through the photonic crystal layer from the LED, wherein the LED and the laser are formed monolithically and the LED acts as an optical pump for the laser.
