NON-HERMETIC PACKAGING FOR LITHIUM NIOBATE-BASED DEVICES

A lithium niobate-based electro-optic device is formed to include a parylene conformal coating layer, as a sealant against moisture. The use of parylene (preferably, parylene-C) has been found to form an acceptable moisture vapor barrier without the need for additional hermetic packaging of the elec...
