Methods of forming lanthanum-modified lead zirconium titanate (PLZT) layers, devices with PLZT layers, and precursor formation solutions

摘要

Methods and solutions for forming lanthanum-modified lead zirconium titanate (PLZT) layers are disclosed. The PLZT layers are highly transparent to 1550 nm wavelength light, and have high crystal quality. Loss factors as low as 0.25 dB per mm are achieved. Fast and low-cost methods are disclosed for making the layers. Devices structures using the layers are also disclosed.
