From: Near-field cavity optomechanical coupling in a compound semiconductor nanowire
a Scanning microscope image of as-grown InP/InAs heterostructured nanowires and a schematic of the internal structure of a nanowire. The crystal orientation for the growth direction [111] and direction of cleaved surface [110] are represented by yellow vectors. The inset shows a cross-sectional image of a nanowire. b Transmission spectrum of the optical cavity with a microscope image of it (inset). c Illustration of the configuration of the microsphere and nanowire with coordinates defined such that the radial direction of the whispering-gallery mode corresponds to the x-axis. d Schematic of optical measurement setup with a fiber-based balanced homodyne interferometer. ECDL external cavity diode laser, EOM electro-optic modulator, BS beam splitter, FL fiber loop.
