  Double-layer quantum Hall systems at total filling factor $\nu_T=1$ can
exhibit a commensurate-incommensurate phase transition driven by a magnetic
field $B_{\parallel}$ oriented parallel to the layers. Within the commensurate
phase, the lowest charge excitations are believed to be linearly-confined Meron
pairs, which are energetically favored to align with $B_{\parallel}$. In order
to investigate this interesting object, we propose a gated double-layer Hall
bar experiment in which $B_{\parallel}$ can be rotated with respect to the
direction of a constriction. We demonstrate the strong angle-dependent
transport due to the anisotropic nature of linearly-confined Meron pairs and
discuss how it would be manifested in experiment.
