Abstract

In this paper, attenuation characteristics of silica-based variable optical attenuator (VOA) with heat insulating structures are investigated by variations of structural parameters and heating power at wavelength 1.55${\mu}m$. The characteristics of power dissipation and attenuation at this VOA was optimized in terms of heating insulating width, under-cladding height and over-cladding height. The optimized maximum attenuation of this VOA was achieved about 31dB at heating power 150mW.
