Abstract :
We have successfully demonstrated experimentally the fabrication and measurement of high quality-factor one-dimensional photonic crystal/photonic wire extended cavities based on silicon-on-insulator. The cavities that we have investigated ranged from 3 to 8 ??m in length. A quality-factor of nearly 74 000 was measured at a cavity length of 5 ??m through the use of tapering both within and outside the cavity, showing good agreement with the finite-difference time-domain simulation approach used.
