Society of Photo-Optical Instrumentation Engineers. The main characteristics required for a diffraction grating used for demultiplexing functions in spectral equalizing systems are investigated, both theoretically and experimentally. We show that volume-phase holographic VPH gratings can be used as dispersive elements instead of classic reflection surface-relief gratings presently employed in most optical telecommunications devices. A design method for this type of diffraction grating and experimental results are presented, confirming that VPH gratings are well suited to such applications.
