Facilitation of Luminance Grating Detection by Induced Gratings
Vision Research, 1996 Grating induction causes a homogeneous test field surrounded by sinewave gratings to possess an induced counterphase grating [McCourt M. E. (1982). Vision Research, 22, 119]. There is currently no consensus about the stage of visual processing at which illusory phenomena such as simultaneous brightness contrast are signaled.

Inverse design and implementation of a wavelength demultiplexing grating coupler [PDF]
Scientific Reports, 2014 Nanophotonics has emerged as a powerful tool for manipulating light on chips. Almost all of today's devices, however, have been designed using slow and ineffective brute-force search methods, leading in many cases to limited device performance.

Band-edge-induced Bragg diffraction in two-dimensional photonic crystals [PDF]
, 2006 Two-dimensional photonic crystals composed of two orthogonal volume diffraction gratings have been photogenerated in photopolymers. When the read beam is set at the Bragg angle, the diffraction efficiency of the transmission grating is strongly enhanced ...
