对基于InP的二维光子晶体板条激光器进行了优化，使其在泵浦和激光两个波长上都表现出低的群速度模。在脉冲区，激光运转波长为1566 nm。在比激光光子模低1个纵向光学声子能量的束缚量子阱电子能级的光子模下泵浦，得到了4kW/cm2的阈值。
An InP-based two-dimensional photonic crystal slab laser is optimized in order to exhibit low group velocity modes both at the pumping and the lasing wavelength. Laser operation is demonstrated at 1566nm in the pulsed regime. A threshold of 4kW∕cm2 is demonstrated by pumping at the photonic mode lying in the bound quantum well electronic levels, one longitudinal optical phonon energy below the lasing photonic mode.
