In this work, controllable fabrication of the microfiber laser arrays in polymer matrix is achieved by employing the advanced spiral drawing technique. Besides the high-quality whispering gallery mode (WGM) lasing, wavelength tuning is also realized by applying external forces on the polymer matrix, which induce slightly enlarged cavity sizes. Furthermore, the perspectives of utilizing the microfiber arrays as force and strain sensors are discussed and demonstrated. � 2017 Optical Society of America.EnglishOptical resonatorsCost-efficientExternal forceMicrofiber arraysResearch fieldsSensing applicationsStrain sensorsWavelength tuningWhispering-gallery-mode lasingWhispering gallery modesArticle10.1364/OE.25.002618
