Research Abstract

Silicon light emitting diodes (LEDs) with photonic crystal (PhC) and PhC nanocavity were demonstrated for the first time. These LEDs exhibited much stronger electroluminescence (EL) than Si LEDs without PhC patterns. Moreover, direct modulation of the Si nanoacvity LED up to 100 MHz was demonstrated.
