Abstract :
Second harmonic generation (SHG) based on the enhancement of the local fields of nanoscale periodic, GaAs-filled holes in a metal film is presented. The highest SHG conversion efficiency achieved was 10−5 at 8 GW/cm2 input peak power, limited by multi-photon absorption and the resultant free-carrier absorption.
