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.

IEEE Photonics Journal, 2013 The acousto-optic mode coupling in grapefruit microstructured optical fibers (GMOFs) has been investigated. Due to the presence of grape-like large air holes in the fiber cladding, unequal acoustic modulation is generated, and orthogonal acoustic ...

Electrically-controlled suppression of Rayleigh backscattering in an integrated photonic circuit
NanophotonicsUndesirable light scattering is a fundamental cause for photon loss in nanophotonics. Rayleigh backscattering can be particularly difficult to avoid in wave-guiding systems and arises from both material defects and geometric defects at the subwavelength ...

A Comparison of Acoustic Field Measurement by a Microphone and by an Optical Interferometric Probe
Acta Polytechnica, 2002 The objective of this work is to show that our optical method for measuring acoustic pressure is in some way superior to measurement using a microphone. Measurement of the integral acoustic pressure in the air by a laser interferometric probe is compared

Acousto-Optical Properties of Metamaterials
Физические основы приборостроения, 2015 The possibility of the effective use of metamaterials in acousto-optics is demonstrated. It is shown that photoelastic constants that determine a change in the dielectric constant of a heterogeneous medium under the action of a sound wave can significantly exceed the corresponding constants for conventional crystals.

Scan-less microscopy based on acousto-optic encoded illumination
NanophotonicsSeveral optical microscopy methods are now available for characterizing scientific and industrial processes at sub-micron resolution. However, they are often ill-suited for imaging rapid events.
