In this paper we describe for the first time the design, fabrication and initial characterization results of a novel gimbal-less, thermally actuated micromirror developed for optical coherence tomography (OCT) application. We report large deflection angle of up to 30° that has been achieved at low input power of less than 17mW and voltage of less than 1V. Moreover, this device has a potential of integration with GaAs/Si substrate due to moderate temperatures developed during its operation-less than 100°C increase with respect to ambient at angular deflection of 30°.
