If a single photon impinges on a Mach-Zehnder interferometer, the probability of detecting the photon in a certain output channel depends on the difference between the phase delays imposed by the two interfering channels. The photon behaves as if it goes through both interfering channels. On the other hand, if detectors are inserted into each interfering channel, the photon is only detected in ...

We consider a subgroup of unitary transformations on mode light induced by Mach-Zehnder Interferometer and an algebra observables describing photon-number detector preceded the interferometer. explore uncertainty principles between such their usefulness in performing Bell-like experiment to show violation Clauser-Horne-Shimony-Holt (CHSH) inequality under physical assumption that distinguishes ...

Two active Mach-Zehnder interferometers are integrated in a monolithic InP/InGaAsP photonic integrated circuit. Together they form a crucial component for optical signal processing: an optical memory element or set-reset flip-flop. The switching time for this initial device is approximately 200 ps. The photonic integrated circuit contains active and passive optical components, including electro...

We suggest a self-testing teleportation configuration for photon qubits based on a Mach-Zehnder interferometer. That is, Bob can tell how well the input state has been teleported without knowing what that input state was. One could imagine building a ‘‘locked’’ teleporter based on this configuration. The analysis is performed for continuous variable teleportation but the arrangement could be ap...

In this paper, we demonstrate two subsystems based on Silicon Photonics, towards meeting the network requirements imposed by disaggregation of resources in Data Centers. The first one utilizes a 4 × 4 Silicon photonics switching matrix, employing Mach Zehnder Interferometers (MZIs) with Electro-Optical phase shifters, directly controlled by a high speed Field Programmable Gate Array (FPGA) boar...

Silicon based ARROW-A structures have been designed in order to obtain a high sensitive integrated optical transducer for sensing applications. The sensor has a Mach-Zehnder interferometer configuration. The optical waveguides that confonn its structure have to verify two conditions: monornode behaviour and high surface sensitivity. In this paper we present a theoretical simulation of the propa...

An ultra-compact optical quantum router (QR) consisting of a Mach–Zehnder interferometer (MZI) and waveguide tapers is proposed numerically simulated, using silicon-on-insulator (SOI). The designed to work at the center wavelength 1550 nm with visibilities 99.65% 98.80% for TE TM polarizations, respectively. Using principle phase compensation self-image, length shortened by an order magnitude t...

Integrated label-free photonic biosensors provide an excellent limit of detection in combination with a low-cost disposable. Their application has thus far been limited by the necessity of an expensive tunable laser. In this article, we present a novel sensor, eliminating the tunable laser by combining a sensitive Mach-Zehnder interferometer with a broadband light source and an on-chip spectral...
