Non-uniform surface relief gratings were laser-inscribed on azobenzene molecular glass thin films using a modified Lloyd’s mirror interferometer. The azobenzene films were exposed to an adjustable interference pattern obtained from the recombination of collimated and spherically divergent laser beams. The localized pitch, grating vector orientation and depth of several non-uniform gratings, with central pitches ranging from 500 nm to 2000 nm, were measured and characterized experimentally. These gratings exhibited a chirping or pitch variation along the imposed X-axis as well as an angular change in the grating vector orientation along the imposed Y-axis.
