Heterodyne Holography with full control of both signal and reference arms
, 2015 Heterodyne holography is a variant of phase shifting holography in which reference and signal arms are controlled by acousto optic modulators. In this review paper, we will briefy describe the method and its properties, and we will illustrate its ...

ACOUSTO-OPTIC FREQUENCY MODULATOR
2012 Solid-State, Actuators, and Microsystems Workshop Technical Digest, 2012 Frequency modulation of a continuous wave laser source enables generation of photons at multiple frequencies from a single pump laser. Such multiple closely spaced laser lines are important for high data rate QAM in dense-WDM networks. In this paper we present a monolithic silicon acousto-optic frequency modulator (AOFM) operating at 1.09GHz.

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection
Advanced Materials, EarlyView.Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Additive Manufacture of Diamond:Titanium Hybrid Quantum Sensors
Advanced Materials Interfaces, EarlyView.ABSTRACT Additive manufacture represents one of the most advanced techniques for the creation of complex parts for applications as diverse as aerospace and implant surgery. However, a challenge with bespoke manufacture of metal parts is the incorporation of sensor elements in a fashion compatible with the 3D printing process.

Holographic imaging of cylindrical ultrasonic waves
Archives of Acoustics, 2014 This report is devoted to the visualisation of standing cylindrical ultrasonic wave, generated by a radially vibrating piezoelectric shell, by means of time-average holographic interferometry. The theoretical basis of this technique was introduced, and

Direct Mode‐Resolved Measurement of Interfacial Phonon Transport by Acoustic Phonon Reflectometry
Advanced Materials Interfaces, EarlyView.We introduce a novel analysis, acoustic phonon reflectometry, that measures the mode‐resolved phonon reflection coefficient at semiconductor interfaces. In aluminum nitride, we observe excellent agreement with the acoustic mismatch model across three distinct interfaces.

Deep and optically resolved imaging through scattering media by space-reversed propagation
, 2012 We propose a novel technique of microscopy to overcome the effects of both scattering and limitation of the accessible depth due to the objective working distance.

Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...
