Source:IEEE Photonics Conference, p.ThZ1 (2011)
We present an integrated transmission filter using phase-shifted Bragg gratings in silicon-on-insulator waveguides fabricated by deep-ultraviolet lithography. The measured resonant transmission band has a narrow linewidth of ~15 pm with a quality factor of ~100,000.
