The next generation of innovative photonic devices will make use of high quality engineered materials like photonic crystals, metamaterials, and metals that support surface plasmon resonancesA number of exciting design opportunities have presented themselves with the advent of engineered photonic materials. Such engineered materials have become more accessible through materials affording high index contrasts and interesting dispersion properties, suitable for processing with advanced semiconductor fabrication techniques. With the high index contrasts provided by semiconductors and metals, together with wavelength scale patterning, researchers are actively exploring engineered photonic materials. Photonic crystals, where the refractive index variation is varied periodic on a length scale on the order of the wavelength of light, are naturally occurring but can also man-made in a variety of materials, including semiconductors like silicon. Metamaterials are effective materials where the optical material properties can be tailored by varying the refractive index of the material on a length scale much shorter than the wavelength of light. As a result of the wavelength or subwavelength patterning, the design of photonic crystals and metamaterials requires a fully-vectorial simulation and analysis

| “"We use Lumerical's FDTD Solutions to solve Maxwell's equations for light transmission through arrays of subwavelength openings of various shapes. Our primary focus is on the basic physics of the light transmission and what parameters are critical to light transmission optimization and suppression, but we also have interest in studying radiation pressure and electromagnetic momentum transfer in metamaterials and bow-tie antennas." - Dr. John Weiner, National Institute for Standards and Technology |

Metamaterials are of large scientific interest as the dielectric response of those materials can be engineered through semiconductor manufacturing to yield interesting physical phenomena at optical wavelengths.
Photonic crystals offer designers the ability to engineer the dispersion of these engineered materials in order to generate interesting spectral behaviour of components constructed with photonic crystal patterning.
Surface plasmons, coherent oscillations of electronic charge bound to the surface of a metal which give rise to scientifically- and industrially-interesting optical phenomena, can be accurately detailed with Lumerical's photonic design solutions.
