“…In the current experiment, we chose a dielectric-loaded SPP waveguide (DLSPPW) [19] to test the bosonic properties of the single plasmons. A DLSPPW is a typical sub-wavelength plasmonic waveguide that is formed by placing a dielectric ridge on top of a thin metal layer.…”

Quantum photonic integrated circuits (QPICs) based on dielectric waveguides have been widely used in linear optical quantum computation. Recently, surface plasmons have been introduced to this application because they can confine and manipulate light beyond the diffraction limit. In this study, the on-chip quantum interference of two single surface plasmons was achieved using dielectric-loaded surface-plasmon-polariton waveguides. The high visibility (greater than 90%) proves the bosonic nature of single plasmons and emphasizes the feasibility of achieving basic quantum logic gates for linear optical quantum computation. The effect of intrinsic losses in plasmonic waveguides with regard to quantum information processing is also discussed. Although the influence of this effect was negligible in the current experiment, our studies reveal that such losses can dramatically reduce quantum interference visibility in certain cases; thus, quantum coherence must be carefully considered when designing QPIC devices.Photonic integrated circuits (PICs), in which multiple photonic functional components comprise a single chip, have attracted considerable attention owing to their small footprints, scalability, reduced power consumption, and enhanced processing stability. In addition to their wide application in classical information processing, integrated photonic quantum logic gates and Shor's quantum factoring algorithm have been demonstrated on these chips [1, 2]; thus, they show great feasibility and high operation fidelity. More recently, much effort has been dedicated to surface plasmon polaritons (SPPs), which are electron density waves excited at the interface between a metal and a dielectric material [3]to further condense PICs beyond the diffraction limit. Not only can SPPs confine light at the nanoscale [4], they are also useful for integrated polarization-controlling devices [5,6]. Studies using periodic metallic hole arrays provided the first experimental evidence that quantum entanglement can be preserved in the photon-SPP-photon conversion process [7][8][9]. Furthermore, the nonclassical statistics of SPPs have been demonstrated using basic quantum Hong-Ou-Mandel (HOM) interference [10], in both long-range plasmonic waveguides (weakly confining waveguide) [11] and sub-wavelength metal plasmonic waveguides [12]. These studies indicate that assembling quantum PICs (QPICs) using plasmonic components is possible.However, two obstacles remain that hinder the development of SPP-based QPICs. The first is that the experimental raw visibility of the quantum interference realized in plasmonic waveguides is below 50% [12], which is the boundary between classical and quantum interference. This low visibility is not compelling evidence that single plasmons are usable for quantum information processing. Interference visibility is so important that higher quantum interference visibility implies higher operation fidelity and a higher probability of success. For example, the HOM interference with 95% visibility * renxf@ustc.edu.c...

“…However, a limiting factor which has prevented ubiquitous adoption of integrated optical components is the restriction on the minimum size of components due to the diffraction limited nature of light. As a potential solution to the disparity between the size scales of photonics and electronics, plasmonics presents the ability to tightly confine and guide light at the nanoscale by coupling with the momentum of free electrons at a metal-dielectric interface, called surface plasmon polaritons (SPPs) (see reviews of waveguide structures [4][5][6]). …”

“…In designing of building blocks for future generation of integrated optical components and devices, plasmonic waveguides play a significant role. Recently, several types of waveguides were discovered such as slots [5,6], plasmonic wedge waveguide [7], and dielectric ridge on the metal surface [8], but among all these waveguides the metal-insulator-metal (MIM) waveguide is generally preferred due to its their exceptional property of confining the surface plasmons to a deep subwavelength scale [9][10][11][12][13]. In these waveguides, propagation is achieved by using even modes due to their low-loss confinement profile.…”

Plasmonic metal-insulator-metal (MIM) waveguides sustain excellent property of confining the surface plasmons up to a deep subwavelength scale. In this paper, linear and S-shaped MIM waveguides are cascaded together to design the model of Mach-Zehnder interferometer (MZI). Nonlinear material has been used for switching of light across its output ports. The structures of even and odd parity generators are projected by cascading the MZIs. Parity generator and checker circuit are used for error correction and detection in an optical communication system. Study and analysis of proposed designs are carried out by using the MATLAB simulation and finite-differencetime-domain (FDTD) method.
