Single-Mode-Fiber-Based Mach-Zehnder Interferometer Setup for Correlation Measurements for Single CdTe/ZnTe Quantum Dots

We report on design and construction of a single-mode-fiber-based Mach-Zehnder interferometer system for measuring single photon indistinguishability from quantum dots emitting in visible spectrum (630±50 nm). The performance of the instrument was tested for its efficiency and usability in single-photon correlation measurements in a proposed experimental setup.
