Abstract

Pulsed-photoabsorption induced disordering (P-PAID) is a laser induced disordering (LID) technique whereby the absorption of high-energy pulses from Nd:YAG laser pulses causes bond breaking and lattice disruption leading to an increased density of point defects. To demonstrate this technique, a laser structure grown by metal-organic chemical vapor deposition (MOCVD) on an InP substrate is studied. Raman spectroscopy demonstrates that the spatial resolution of P-PAID technique is better than 2.5 μm.
