Influence of Absorption on the Total Reflection Tunneling Effect of 1D Photonic Crystal

By introducing the concept of complex refractive index,the influence of absorption on the total reflection tunneling effect of 1D photonic crystal was studied by the characteristic matrix method.The response curves of the total reflection tunneling versus extinction coefficient and cycle optical thickness were calculated.It is indicated that the peak height of total reflection tunneling decreases with the increasing extinction coefficient,but its frequency is independent of the extinction coefficient.The frequency and frequency width of total reflection tunneling decrease with the increase of the cycle optical thickness.
