Evolution of the Fraunhofer pattern across different devices. Comparison of the evolution of the Fraunhofer pattern when B_y is applied to devices 1–4. The experimental data (a–d) agrees well with the normalized differential resistance of the simulations (e–h) that are based on a finite momentum shift model and take into account width asymmetries delineated in Table 1. An additional tilt is added to the simulations for better comparison with the data. (A possible origin for the tilt is a flux asymmetry, which is difficult to quantify.) In all the devices, side branches with slope m appear as an in-plane field B_y is added. The appearance of these side branches is indicative of interference in the phase modulation due to B_z and B_y
