Optically pumped lasing of pyrromethene 597 in 2D columnar photonic crystals (PCs) derived from holographic polymer‐dispersed liquid crystals (LCs, see Figure) exhibit resolution‐limited linewidths of 1.9 nm and thresholds of less than 200 μJ cm –2 . Electric field modulation of the LC directors allows tuning of the laser mode over 5 nm. Use of PC properties that go beyond those associated with the photonic bandgap may lead to organic‐based PCs for linear/nonlinear nanophotonics.
