Slow Photon Generation on Silicon NanoPhotonic Crystal Waveguides and Applications

Photonic crystal line defect waveguides show high group velocity dispersion and slow photon effect near transmission band edge. The group index of the fabricated silicon photonic crystal line defect waveguide is experimentally demonstrated as high as 45 at optical wavelength around 1558 nm. The group velocity dispersion of the fabricated silicon photonic crystal line defect waveguide is as high as 50 ps/nm·mm at wavelength around 1558 nm, which is more than 10 times the dispersion of the standard telecom fiber (D = 3 ps/nm·km). Due to the integration nature of photonic crystals, system-on-chip integration with multifunction including modulation, switching, delay manipulation, and detection can be easily achieved. Further results will be presented in the plenary session of the conference.
