We present a novel optical microfabrication technology to directly print polymer suspended-mirror devices (SMDs) on the end face of fiber-optic ferrules. With an own-established optical 3-D μ-printing platform, three kinds of ferrule-top SMDs were rapidly fabricated by using SU-8 photoresist. Optical reflection spectra of the fabricated SMDs were measured and then analyzed by using fast Fourier transform. The application of the ferrule-top SMD as a miniature displacement sensor was experimentally demonstrated.
