Extended Data Fig. 5: Simulations of band structure measurements with different input polarizations.
From: Non-Abelian lattice gauge fields in photonic synthetic frequency dimensions
We calculate and plot \(\mathop{\xi }\limits^{\approx }(\delta \omega ,t)\) as described in this figure. The input polarizations are set to be H (horizontally polarized), X (+45° linearly polarized), Y (+135° linearly polarized), L (left circularly polarized), and R (right circularly polarized). The results of vertically polarized input are shown in Fig. 3c. We take the modulation strength g = 0.14 ΩR and round trip power loss in the resonator as 1.74 dB. For each value of φ, the colour scale is the same as that in Fig. 3c to facilitate the comparison between conditions where φ is identical but ψin is different.
