Abstract

We introduce an optomechanical transducer-based nanoscale cantilever for atomic force microscope (AFM). The high optical quality factor of the microdisk resonator enables detection of the nanoscale cantilever motion with high sensitivity. A low stiffness (approximately 1 N/m) and high frequency (above approximately 4 MHz) nanoscale cantilever provides a wide bandwidth for fast motion detection without sacrificing force sensitivity. We demonstrate the capabilities of the device in AFM for fast scanning (nominal 30 μm × 30 μm, 39.06 Hz line rate, 2.93 mm/s tip speed) with a fast settling time (
