Abstract :
The first observation, to the authors´ knowledge, of laser emission in a defect-free deep-etched 2-dimensional photonic crystal is reported. The structure explored here consists in a triangular lattice of 4.5 μm-deep air holes drilled in a low index contrast InP-based waveguide. Simultaneous guided and vertical directions laser operation is demonstrated at room temperature. A laser threshold of 15 kW/cm2 (average intensity) is measured with a pump diameter corresponding to only 9 periods of the photonic crystal.
