With a 10\u2009mm optical aperture, the device employs a gimbal structure driven by orthogonal magnetic field components to achieve biaxial decoupling and high linearity. A bipolar magnetic configuration augments the driving torque, providing sufficient design margin for the torsion axis while reducing power consumption. Additionally, T-shaped torsion beams are utilized to enhance shock robustness without compromising the scanning range. Experimental results demonstrate a mechanical tilt of \u00b12.3 mrad@\u00b152 mA with a low holding power of 54 mW per axis. Nonlinearity is only 0.04%. Resonant frequencies of 598\u2009Hz and 819\u2009Hz are achieved, enabling a rise time of 0.38\u2009ms and a closed-loop 2% settling time of approximately 1.0\u2009ms. Furthermore, the structural failure of the torsion beams was observed at a shock load of 960\u2009g. This work provides a robust, power-efficient, and high-precision beam-steering solution for optical communication terminals on small LEO satellites.<\/jats:p>","DOI":"10.1364\/ol.597626","type":"journal-article","created":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T13:00:06Z","timestamp":1777554006000},"page":"3032","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A high-linearity, low-power 10-mm MEMS fast steering mirror with enhanced shock robustness for space laser communications"],"prefix":"10.1364","volume":"51","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-9253-8822","authenticated-orcid":true,"given":"Jiapeng","family":"Hou","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04c4dkn09","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Chinese Academy of Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haoxiang","family":"Li","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04c4dkn09","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Chinese Academy of Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yantao","family":"Dong","sequence":"additional","affiliation":[{"name":"Shanghai Radio Equipment Research Institute"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoxia","family":"Wu","sequence":"additional","affiliation":[{"name":"China Academy of Space Technology (Xi\u2019an)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Qian","sequence":"additional","affiliation":[{"name":"East China Institute of Photo-Electron IC"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenjiang","family":"Shen","sequence":"additional","affiliation":[{"name":"Chinese Academy of Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huijun","family":"Yu","sequence":"additional","affiliation":[{"name":"Chinese Academy of Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,5,18]]},"reference":[{"key":"ol-51-11-3032-R2","doi-asserted-by":"publisher","first-page":"7303009","DOI":"10.1109\/JPHOT.2023.3291807","type":"journal-article","volume":"15","author":"Lee","year":"2023","journal-title":"IEEE Photon.
