Dr. Raymond Rumpf recently travelled to Bangkok, Thailand to present a workshop on finite difference frequency domain (FDFD) to students at Bangkok University. Every student left with a working simulation of a diffraction grating.

Diffraction gratings are common optical elements in spectrometers, fan-out gratings, dichroic mirrors, and other filter devices. One common aspect of all of these is that they split an incoming wave into multiple diffraction orders. The direction of the diffraction orders depends on the angle of incidence and period of the grating relative to the wavelength. […]

Dr. Raymond C. Rumpf has been promoted to Fellow of the International Society for Optics and Photonics (SPIE), an educational nonprofit established to advance light-based science, engineering, and technology. Fellows are members of distinction who have made significant scientific and technical contributions in the multidisciplinary fields of optics, photonics, and imaging. They are honored for […]
