DOI: 10.1109/lpt.2017.2685458
Abstract: This letter reports the demonstration of a novel method to passively tune the splitting ratio of a Ti-indiffused lithium niobate (LiNbO3) 3-dB directional coupler by the addition of a silicon-rich nitride cladding material. Plasma-enhanced chemical… read more here.
