Abstract

The application of lithium niobate thin film is a hot topic now. Due to its superior electro-optic modulation properties, it has many popular applications in integrated optics. However, LN thin film’s small size also produces major challenges when attempting to efficiently couple light with optical fibers. Therefore, a trident edge coupler for LN thin-film is proposed in this paper, and its performance is studied in simulation. The trident edge coupler shows

Abstract

The I-V characteristics of K(Ta 0.65 Nb 0.35 )O 3 thin films being prepared by PLD method on Si(100) were found to be Ohmic at low fields and space-charge-limited at higher fields, and this phenomena was correctly explained by SCLC theory.
