Abstract [en]

We demonstrate continuous wave with an external efficiency over 0.15 W/A and monomode operation of a full photonic crystal (PhC) laser. The optical confinement and a wavelength selectivity better than 25 dB are all ensured by a unique PhC. We take advantage of the feedback on the fundamental mode which exists within the photonic gap for some specific designs of the PhC guide. These designs are calculated using the plane wave expansion method.
