Acousto-Optic Tunable Filters Spectrally Modulate Light
ثبت نشده
چکیده
The development of opt electronic technology in the past two decades has intensified research on devices that control and manipulate optical radiation. Acousto-optic devices are based on acousto-optic effects in which the optical medium is altered by the presence of ultrasound. Examples of acousto-optic devices include optical modulators, deflectors, scanners, Q-switches, isolators, and frequency shifters. These devices have many applications in high-speed laser printers, laser lithography, optical communications and computing, large-screen laser projectors, frequency shifting, particle inspection, optical spectrum analysis, signal processing, and radar, range finder, and target designation.

Acousto-optic Tunable Switch for WDM Applications
polarization diversity AOTF in the passive, or bar, state, and (d) in the active, or cross, state. Abstract: An acousto-optic tunable switch (AOTS) can provide highly selective wavelength switching and wavelength routing in optical DWDM systems. This paper presents the basic concept of AOTS and a simple analysis of the phase mismatch and wavelength deviation in WDM systems using acousto-optic t...
متن کاملAxial strain dependence of all-fiber acousto-optic tunable filters.
We report the axial strain dependence of two types of all-fiber acousto-optic tunable filters based on flexural and torsional acoustic waves. Experimental observation of the resonant wavelength shift under applied axial strain could be explained by theoretical consideration of the combination of acoustic and optical effects. We discuss the possibility of suppressing the strain effect in the fil...
متن کاملPolarization-independent imaging with an acousto-optic tandem system.
We propose a method for filtering convergent light beams with arbitrary polarization. For this purpose, a tandem of similar acousto-optic tunable filters was applied. Owing to the special mutual orientation of the cells, two coincident beams with ordinary and extraordinary polarizations were diffracted by the first crystal and the second crystal, respectively.
متن کاملAdvanced spectral processing of broadband light using acousto-optic devices with arbitrary transmission functions.
In the paper, we developed a dispersive method for transmission function synthesis of collinear and quasi-collinear acousto-optic tunable filters. General theoretical consideration was performed, and modelling was made for broadband and narrowband signals. Experimental results on spectral shaping of femtosecond laser emission were obtained. Binary spectral encoding of broadband emission was dem...
متن کاملAll - Fibre Acousto - Optic Tunable Filter Based on a Null Coupler
Tunable acousto-optic spectral filters based on null couplers have been improved by making the coupler more uniform. A new double-pass arrangement further narrows the bandwidth, reduces the sidelobes to -20 dB and doubles the frequency shift,
