All-optical flip-flop based on coupled SOA-PSW

Abstract: Abstract:The semiconductor optical amplifier (SOA) has obvious advantages in all-optical signal processing, because of the simple structure, strong non-linearity, and easy integration. A variety of all-optical signal processing functions, such as all-optical wavelength conversion, all-optical logic gates and all-optical sampling, can be completed by SOA. So the SOA has been widespread concerned in the field of all-optical signal processing. Recently, the polarization rotation effect of SOA is receiving conside… Show more

“…Although the work is excellent, it still lacks advanced applications in terms of device miniaturization up to a deep subwavelength scale (hence overall design of device remains in thousand of micrometers), and due to the presence of electrical signals for altering the refractive index of waveguides, it limits the speed of device. Some switching circuits were also proposed by using semiconductor optical amplifier (SOA) but they were backsitted due to the phenomenon of gain saturation [21]. All optical logic gates were also proposed using photonic crystal but being lack of the nonlinear material inside the structure will enable the switching of optical signals for complex circuits [22].…”
