Another device, the flexible distributed Bragg reflector laser with an active layer structure supporting second-order feedback, makes full use of the advantageous properties of polymers, namely flexibility, large-area fabrication, and low-cost processing [41, 42]. As can be seen in Fig. 6.15, the device consists of a one-dimensionally periodically structured flexible substrate coated with an m-LPPP layer, which acts as a planar wave guide. The substrate possesses a periodic height modulation with a period of A = 300 nm. 

HPDLCs have periodic refractive index distribution by polymer-rich layer and LC-rich layer, so they can be used as DFB laser cavities. In the DFB laser cavity, the light feedback for lasing modes relies on Bragg scattering by the periodic microstructures [78,79]. The DFB lasing wavelength from the device should satisfy Bragg condition [80]...
