Abstract

We report experimental measurements of slow light in Comb Photonic Crystal Waveguides (CPCW). The tailoring of the slot into a comb allows performing dispersion engineering in order to achieve slow light regime, and efficient tapers allow a high coupling efficiency. We also investigate the losses with cut-back measurements and show that losses are comparable with those of a standard W1 Photonic Crystal Waveguide, whereas the nonlinear effective area is strongly reduced. This type of waveguide offers opportunities to realize compact devices with an ultra-high light confinement for achieving optical nonlinearities with a low index material.
