Abstract :
We introduce and demonstrate experimentally that 2-D photonic crystals (PhC) allow the integration of single-mode distributed-feedback (DFB) lasers with both a precise control of the emission wavelength and a high robustness toward optical feedback. This work is based on double deformation , a novel approach, offering theoretical Q-factors above 6×105 for high volume guided mode. Experimentally, DFB lasers on a GaAs membrane, lasing around 1 μm, show stable single-mode emission with unaltered performances under high optical feedback of around 15% in energy.
