Design of parity generator and checker circuit using electro-optic effect of Mach–Zehnder interferometers

A simple, label-free, electrochemical DNA parity generator/checker for error detection during data transmission based on “aptamer-nanoclaw”-modulated protein steric hindrance

“…During any kind of data transmission, the occurrence of erroneous bits (which have severe impacts on normal logic computing) is an unavoidable problem 24–27. Luckily, these bits can be detected via placing a parity generator (pG) at the sending module and a parity checker (pC) at the receiving module.…”

“…During any kind of data transmission, the occurrence of erroneous bits (which have severe impacts on normal logic computing) is an unavoidable problem. 24 – 27 Luckily, these bits can be detected via placing a parity generator (pG) at the sending module and a parity checker (pC) at the receiving module. As described in the pG/pC operating principles, 24 – 29 an even pG could generate an additional parity bit (P) and add it to the initial binary bits Dn, changing the number of 1's ( Σ ) in the DnP string to even.…”

A DNA-based parity generator/checker for error detection through data transmission with visual readout and an output-correction function

“…Firstly, most of the previously developed pG/pC systems have been based on semiconductor substrates, in which the optical inputs were processed by a Mach–Zehnder interferometer or an optical amplifier and so on. 17 , 19 – 23 The indirect optical outputs of most semiconductor pG/pC systems were often recorded by cumbersome instruments and were difficult to visualize by the naked eye, which restricted the potential practical applications. Secondly, in 2013, Pischel and coworkers pioneered the first molecular implementation of pG/pC using the fluorescence of artificially synthesized organic molecules as the output.…”

Modeling of all-optical even and odd parity generator circuits using metal-insulator-metal plasmonic waveguides

“…Thus, by cascading plasmonic DCs and MZIs, all-optical structures of even and odd parity generators are modeled within the footprints of (12510) m and (20510) m, respectively. Recently, some switching circuits have been proposed by using LiNbO 3 -based MZI, which work on the principle of electro-optic effect [20]. 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.…”
