Effect of absorption of dopant on design of photonic crystal filters

LIU Qi-neng

In order to study the effect of dopant absorption on photonic crystal filters,the peak transmissivity and full width at half maxmum(FWHM) of the filters were calculated based on the complex refractive index and the characteristic matrix.It was found that the peak transmissivity decreased with the increment of the extinction coefficient,however the FWHM increased with the increment of the extinction coefficient.Both the peak transmissivity and the FWHM decreased with the increment of the optical thickness of doping.A valuable conclusion is drawn that the absorption of dopant has to be taken into account for the design of a phonic crystal filter and that the extinction coefficient should be less than 0.002 and the optical thickness of doping should be 2(λ0/4) or so.
