Paper Abstract

In this paper, effect of two-dimensional photonic pattern on the properties of the GaAs/AlGaAs based light emitting diode (LED) is demonstrated. The interference lithography was employed to surface patterning of the GaAs/AlGaAs based LED. The active region of the LED includes a GaAs/AlGaAs triple quantum well emitting at 850 nm. Interference lithography was used for preparation of two-dimensional pattern in the upper diode layer. The prepared LED with two-dimensional patterned photonic crystal structure was then investigated by electrical and optical measurements. Prepared photonic crystal LED shows enhanced light extraction efficiency due to the more effective extraction of guiding modes, what was documented from finite difference time domain simulations as well as from L(I) measurements.
