A liquid‐crystalline blue‐phase laser with a tunable photonic bandgap (PBG) of over 150 nm and a wide temperature range is demonstrated by Myoung Hoon Song and Suk‐Won Choi on p. 3002 . A lasing peak shift of more than 100 nm is realized due to the large PBG shift of the liquid‐crystalline blue phase. The shift in the lasing wavelength was reversible during repeated temperature changes over the entire stability range of the liquid‐crystalline cubic blue phase.
