“…The acousto-optic tunable filter (AOTF) has been considered as a strategic optical dispositive for optical communication due your compact size, high-speed switching and wideband wavelength selectivity (Onaka et al 2008;Veeriah et al 2007;Katrasnik et al 2010;Gupta et al 2012;Sabóia and Ferreira 2009;Sobrinho and Sombra 2002;Sobrinho et al 2002;Tran 1997;Jung et al 2005;Yariv and Yeh 1984;Xu and Stroud 1992;Xie et al 2013;Song et al 2014;Mantsevich et al 2015). An all-fiber tunable Mach-Zehnder interferometer based on an AOTF was demonstrated experimentally to have high performance .…”

Optical cryptography under PPM-PAM modulation based in short optical pulses in an acoustic-optic tunable filter (AOTF)

“…While emerging asynchronous transfer mode (ATM) switches and Internet Protocol (IP) routers can be used to switch data using the individual channels (typical rates of 2.5 or 10 Gb/s) within a WDM link, this approach requires tens or even hundreds of switch interfaces to terminate a single link with a large number of channels (Vlachos et al 2003). In this way, various optical devices have been studied for the all-optical signal processing, all-optical logical gates, ultrahigh-speed optical telecommunications, alloptical switching, RF photonic signal processing (Vlachos et al 2003;Boscolo et al 2008;Stampoulidis et al 2007;Menezes et al 2007a;Li et al 2008;Menezes et al 2007bMenezes et al , 2009Almeida et al 2007;Sobrinho et al 2008;Zoiros et al 2006;Clavero et al 2004;Fraga et al 2006;Sobrinho et al 2007Sobrinho et al , 2002bSobrinho et al , 2004Onaka et al 2008;Veeriah et al 2007;Sobrinho et al 2006a;Sobrinho et al 2002a;Gao et al 2006;Menezes et al 2006;Ferreira et al 2009), ultrafast metrology, microwave engineering, image processing and optical computing and already several functions can be accomplished within the optical domain, such as optical power division, ultrafast optical switching, optical connections with photonic gateways and all-optical multiplexing (Vlachos et al 2003;Boscolo et al 2008;Stampoulidis et al 2007;Menezes et al 2007a;Li et al 2008;Menezes et al 2007bMenezes et al , 2009Almeida et al 2007;Sobrinho et al 2008;Zoiros et al 2006;Clavero et al 2004;Fraga et al 2006;…”

“…In this context, acousto-optic tunable filters (AOTF) have been played a strategic role in the scenery of the photonic technology and all-optical devices, arousing the crescent interests of many researchers (Sobrinho et al 2002b(Sobrinho et al , 2004Onaka et al 2008;Veeriah et al 2007;Sobrinho et al 2006a;Sobrinho et al 2002a;Gao et al 2006;Sobrinho et al 2006b;Li et al 2002;Jung et al 2005).

“…An AOTF with an integrated optical waveguide on a lithium niobate substrate brings the advantages of high-speed switching characteristics, wideband wavelength selectivity, and compactness. Waveguide acousto-optic tunable filter (AOTF) has many excellent characteristics as simultaneous multiwavelength selection, a broad tunable bandwidth, and direct wavelength selection without scanning (Onaka et al 2008;Veeriah et al 2007). Even appearing applications with temperature sensing and optical sensors based on AOTF (Sobrinho et al 2006b).…”
