Investigation of the Ga-Sb-S chalcogenide glass with low thermo-optic coefficient as an acousto-optic material

Polarization-Multiplexed High-Throughput AOTF-Based Spectral Imaging System

“…The typical optical aperture limitations for the visible AOTF devices with TeO 2 crystal are a throughaperture of up to 25 × 25 mm 2 [11] and a real aperture angle of 9 • [12]. These constraints are primarily influenced by the properties of the crystal material, and ongoing research explores alternative materials [13,14]. Meanwhile, the extinction design of the system is mainly attributed to the traditional optical design, which only receives a single polarization of light using crossed polarizers.…”

BaO–TeO2–MoO3 glass: excellent candidate for acousto-optic modulators with high diffraction efficiency, fast response, and stable operation

“…At present, most AO devices are based on AO crystals or glasses. [21][22][23] AO glasses exhibit isotropic properties, reduced preparation time, and more economical cost than AO crystals. 24,25 Hence, AO glasses and AOMs have attracted intense research attention.…”

High‐Quality Acousto‐Optic Modulators with High Diffraction Efficiency, Polarization Extinction Ratio, and Small Insertion Loss Based on a Novel BaO–TeO2–WO3 Glass

“…Recently, a series of chalcogenide glasses with large refractive indices have been reported, which exhibit excellent AO figures of merit and wide infrared cut-off edges. [21][22][23][24] More importantly, they do not contain toxic elements that are harmful to human health. However, the transmittance of chalcogenide glasses in the visible and near-infrared bands is not ideal, and it is more suitable for far-infrared bands.…”
