THE birefringence of barium titanate has been measured over the range 4000–7000 A. Our attention was first directed to this work by the impossibility of obtaining the correct colour sequence in ...

To sum up, the researchers demonstrated a novel approach for achieving QGVM SHG in a racetrack resonator and bent waveguide on X-cut TFLN. They leveraged birefringence-induced mode transitions of ...

However, designing high-performance birefringent materials with a birefringence value (Δn > 0.3) is challenging. Achieving superior optical anisotropy requires identifying functional groups with ...
