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.
