Paper Abstract

The temperature-dependent insertion-loss of volume phase holographic wavelength-division demultiplexers(WDDM) is analyzed using Bragg diffraction theory in this paper. We demonstrate that most of the temperature-induced insertion-loss results from the diffraction deflection. Finally, we propose a new way to improve the temperature characteristics of volume phase holographic demultiplexers if we have a suitable choice between the thermal expansion coefficients of the gratings and the thermal coefficients of the gratings index. This result is useful to design a self-temperature compensation WDDM.
