Abstract

We present a detailed design and characterization for a compact X-junction we proposed recently. Even at a wide full-branching angle of 1.4 , simulation predicts the crosstalk and insertion loss to be -20.1 and 0.2 dB, respectively; the wavelength bandwidth is 230 nm (1390-1620 nm). Devices made in polymer realize -16.1-dB crosstalk and 0.3-dB loss.
