Abstract
We introduce and demonstrate a new design for mode multiplexing in proton-exchange lithium niobate waveguides using asymmetric Y-junctions. The coupling between the lowest two modes in the device is suppressed by modifying the Y-junction shape. Without increasing the device length, the mode contrast is enhanced by >3.4dB compared to conventional designs. The new design improves the performance of an important functional block in integrated optics.
