摘要

We investigate the electromagnetic properties of a two-dimensional (2-D) photonic-crystal array of vertical cavities for use in nonlinear optical image processing. We determine the 2-D photonic band structure of the array, and we discuss how it is influenced by the degree of interaction between cavities. We study the properties of defects in the 2-D lattice and show that neighboring cavities interact through their overlapping wave functions. This interaction can bo used to produce nearest-neighbor nonlinear Boolean functions such as AND, OR, and XOR, which are useful for optical image processing. We demonstrate the use of 2-D photonic bandgap structures for image processing by removing noise from a sample image with a nearest-neighbor AND function. # 1998 Optical Society of America OCIS codes: 070.4340, 100.2000, 100.2550, 190.0190, 200.3760, 200.4690.
