抄録

We reported the solid-state laser composed of an Al2NO 3 photonic crystal and an organic gain medium. The photonic crystal was fabricated through the impinging technique and electrochemical process, which do not require any elaborate process used in the lithographic device technology, but they are effortless for transferring the periodic pattern in the photonic crystal and controlling its photonic band gap. When the photonic crystal was infiltrated with the organic gain material, we found a laser emission under optical excitation. The minimum laser-threshold was about 2.4 nJ/pulse, where linewidth of laser emission was as narrowed as 0.09 nm. We explain the laser action as due to the photonic band edge effect, and precise control of the laser mode and oscillation wavelength through the control of the photonic stop band and small change in the refractive index of the gain medium.
