Abstract : A photonic crystal filter with silicon as defect layer in third optical window region for C-band applications is proposed and its transmittance spectra is analyzed with respect to structural and temperature variations. We have obtained two channel peaks in optical E and C band regions. Channel properties are plotted with respect to variations in each parameter. The increase in stack number resulted in reduction of separation between two channel peaks. The enhancement in defect film thickness shifted the whole spectra more into infrared region and temperature variations induced a slow drift in wavelength. So effective control of photonic band gap makes the crystal more applicable in the areas of optical communication such as waveguides, optical insulators, splitters, and micro resonators for spontaneous emission management. Also the proposed filter works well in the area of C-band applications such as for WDM system in FTTH.
