Abstract :
Photonic crystals (PhC) create platform for a new generation of optical and optoelectronical devices. The PhC structures have been patterned in GaAs-based light emitting diodes in order to modify their optical properties. Patterned diodes with two-dimensional PhC were investigated by measurements of emission and detection properties. Measured dependencies revealed effect of PhC on emission and photocurrent spectrum.
