Abstract :
We fabricated photonic crystal slow-light waveguide using high-resolution e-beam lithography, and demonstrated a high tunable resolution of 36 by local heating. This value is further improved to 110 by compressing output pulse. We applied it to optical correlator, and observed sub-picosecond pulse at a scanning frequency of 1 kHz.
