A molecularly assembled three-dimensional photonic crystal was prepared in the liquid-crystalline blue phase for organic solid-state laser applications (see Figure). The polymer network in the blue phase stabilized the laser operation over a temperature range 35 °C wide. Narrow laser emission, low threshold response, and circular polarization were measured due to the photonic-bandgap effect of the blue phase of the photonic crystal.
