Paper Abstract

Two optical functional devices based on 2D photonic crystal are investigated. First of all, add-drop filtering devices based on single defects in 2D photonic crystal slabs are characterized. After describing basic characteristics of channel-drop function, we show the improvement of device characteristics through defect engineering. We also demonstrate the channel-add function of the device. Next, we describe a 2D large-area surface-emitting laser exhibiting single-longitudinal and single-lateral mode oscillation with narrow divergence angle based on the 2D coupling effect of lightwave in 2D photonic crystals. A method of controlling the polarization mode by changing the shape of the unit cell is also presented. These results indicate that 2D photonic crystals are useful for the realization of novel optical functional devices.
