| Abstract: |
| A new compact optical Fano filter suitable for biological sensing is proposed, which patterns photon crystal in single crystalline
silicon nanomembranes (SiNMs) and transferring onto transparent glass substrates. The effects of air hole size and silicon
thickness on the transmission characteristics of new filter are numerically investigated by using three-dimensional finite-difference
time-domain (FDTD) technique, the spectral response is also studied by back-filling bio-liquid. The results show that the
dip wavelength will shift toward longer wavelength by either reducing air hole radius or filling bioliquid. The number of
dips will increase with the increase of silicon thickness. The size of proposed filter can be less than 1 mm2.
