Acousto-optic tunable optical diode based on periodically poled LiNbO3

Qin Wang, Fei Xu, Zi-yan Yu, Xiao-shi Qian, Xi-kui Hu, Yan-qing Lu and Hui-Tian Wang National Laboratory of Solid State Microstructures Nanjing University, Nanjing 210093, China Abstract—we propose a bidirectional acousto-optic tunable optical diode based on a periodically poled lithium niobate (PPLN) waveguide with defect. An acoustic wave propagates together with the light beam so that a coll...

Acousto-optical multiple interference devices

We present a new concept for waveguide acousto-optical devices based on coupled Mach–Zehnder interferometers driven by acoustic waves. These acousto-optical multiple interference devices use the periodic refractive index modulation induced by the acoustic wave to realize functionalities such as ON/OFF switching for an arbitrary time interval, as well as for efficient light modulation at high ha...

Optical sensor calibration for electro-optical stomatography

We are currently developing a technology called “electrooptical stomatography” to measure and visualize articulatory movements within the vocal tract using electrical contact sensors and optical proximity sensors. To measure tongue movements with the optical sensors in this system, a mapping between the raw sensor values and actual tongue positions has to be determined. This mapping is non-line...

Self-homodyne RF-optical LiNbO3 microdisk receiver

A novel RF-optical receiver architecture based on nonlinear optical modulation in a LiNbO3 microdisk modulator is presented. This is the first RF-optical receiver without high-speed electronic components for transmitted carrier links. We demonstrate receiver operation by demodulating 50 Mb/s digital data from a 8.7 GHz carrier frequency. 2005 Elsevier Ltd. All rights reserved.

Acousto-optic-assisted diffuse optical tomography.

We introduce and experimentally demonstrate acousto-optic-assisted diffuse optical tomography (DOT) using a holography-based acousto-optic setup. The method is based on probing a scattering medium with a localized acoustical modulation of the phase of the scattered light. The optical properties of the scattering medium are recovered with ultrasound-limited resolution by applying DOT reconstruct...
