Although breaking vertical structural symmetry in BICs\u2010supporting systems can induce asymmetric radiation, the radiated power typically remains partitioned between opposing half\u2010spaces. Furthermore, achieving arbitrary control over the amplitude ratio and phase difference of these counter\u2010propagating beams presents a significant challenge, thereby limiting sophisticated beam manipulation within a single half\u2010space. In this work, we delve into BICs within the superwavelength regime, where photonic structures inherently support multiple diffraction orders. We systematically investigate the far\u2010field polarization states and associated topological properties of these individual diffraction channels. Critically, by engineering a configuration that supports two co\u2010propagating diffraction orders directed into the same half\u2010space, we demonstrate comprehensive and continuous control over the resulting unidirectional guided resonances (UGRs). Full tunability of both the directionality (spanning from \u22121 to 1) and the relative phase difference (spanning from \u2212\u03c0 to \u03c0) between these two co\u2010propagating beams is achieved. This versatile manipulation of multiple beams radiating concertedly into a specific direction opens new avenues for various advanced applications.<\/jats:p>","DOI":"10.1002\/nap2.70014","type":"journal-article","created":{"date-parts":[[2026,3,24]],"date-time":"2026-03-24T09:34:51Z","timestamp":1774344891000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Full
