Ideal for applications such as: Wavelength Selectable Switch (WSS), Re-configurable Optical Add-Drop Modules (ROADM), Tunable Filters, Optical Channel Performance Monitors (OPM, OCM), Optical Spectrum Analyzers (OSA) and Wavelength Blockers, Volume Phase Gratings (VPG®) work much like conventional surface relief reflection gratings, except in transmission. They are periodic phase structures, whose fundamental purpose is to diffract different wavelengths of light from a common input path into different angular output paths.
