In analogy to conventional semiconductor diodes, the Josephson diode exhibitssuperconducting properties that are asymmetric in applied bias. The effect hasbeen investigated in number of systems recently, and requires a combination ofbroken time-reversal and inversion symmetries. We demonstrate a dual of theusual Josephson diode effect, a nonreciprocal response of Andreev bound statesto a superconducting phase difference across the normal region of asuperconductor-normal-superconductor Josephson junction, fabricated using anepitaxial InAs/Al heterostructure. Phase asymmetry of the subgap Andreevspectrum is absent in the absence of in-plane magnetic field and reaches amaximum at 0.15 T applied in the plane of the junction transverse to thecurrent direction. We interpret the phase diode effect in this system asresulting from finite-momentum Cooper pairing due to orbital coupling to thein-plane magnetic field, without invoking Zeeman or spin-orbit coupling.
