12. Owing to their isotropic optical properties associated with their polycrystalline makeup, pristine BPLC [51] has also been employed as the guiding core to fabricate a similar nonlinear fiber array. Dye‐doped BPLC filled capillary (see Figure 1.27) has shown promising possibilities for random laser generation [52].
