In this paper we present fabrication process of photonic crystal (PhC) and photonic quasicrystal (PQC) structures in thin photoresist layer on glass substrate. For fabrication, we used laser interference lithography in Mach-Zehnder configuration. One-dimensional (1D), two-dimensional (2D) PhC and PQC relief structures of period 1600 nm were prepared in photoresist layer with depth up to 1100 nm. Quality...
It was confirmed that photonic crystals (PhC) have the considerable effect on enhancement of extraction efficiency of light emitting diodes (LED) by minimizing the total internal reflection of the light escaping the LED chip. The enhancement of the extraction efficiency requires a structure design that optimizes the interaction of the guided modes with the PhCs. It strongly depends on the structure...
