Abstract

Bulk GaN and InGaN green LEDs are investigated based on two-photon photoluminescence (PL) and current images. The analysis is performed with an inverted microscope and a galvano-mirror based scanning system. A Kerr-lens-mode-locked Ti:sapphire laser provided IR laser pulses of 150 fs tunable between 700-800 nm. Band-pass filters are used to select specific band for PL image.
