However, existing transfer\u2010printing strategies remain fundamentally limited to planar integration, restricting access to orientation\u2010dependent optical functionalities. Here, we introduce a rolling\u2010enabled transfer\u2010printing strategy that enables deterministic nonplanar heterogeneous integration through precise mechanical orientation control at the nanoscale. By exploiting rolling\u2010induced rotation during assembly, identical photonic\u2010crystal nanobeam lasers are integrated onto silicon waveguides in planar or orthogonal configurations, enabling selective coupling to TE\u2010like or TM\u2010like modes without modifying the cavity design or epitaxial structure. Both configurations exhibit stable lasing and polarization\u2010resolved coupling to silicon waveguides, in good agreement with numerical simulations, confirming that mechanical orientation alone can define optical functionality. By establishing orientation control as a new degree of freedom in heterogeneous integration, this work elevates transfer printing from a placement technique to a functionality\u2010defining platform, opening new opportunities for compact, multifunctional, and reconfigurable photonic systems on silicon.<\/jats:p>","DOI":"10.1002\/nap2.70284","type":"journal-article","created":{"date-parts":[[2026,9,5]],"date-time":"2026-09-05T07:22:51Z","timestamp":1788592971000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Rolling\u2010Enabled Nonplanar Heterogeneous Integration for Polarization\u2010Diverse Nanolasers on Silicon Photonics"],"prefix":"10.1002","volume":"15","author":[{"given":"Byoung Jun","family":"Park","sequence":"first","affiliation":[{"name":"KU\u2010KIST Graduate School of Converging Science and Technology Korea University  Seoul Republic of Korea"},{"name":"Physics &amp; Informatics Laboratories NTT Research Inc.
