Single-photon detectors have gained significant attention recently, driven by advancements in quantum information technology. Applications such as key distribution, cryptography, and computation demand the ability to detect individual quanta of light distinguish between single-photon states multi-photon states, particularly when operating within waveguide systems. Although detector fabrication has been established for some time, integrating with waveguides using new materials suitable structural electronic properties, especially at telecommunication wavelengths, creates more compact source-line-detector This review explores state art research examines potential breakthroughs offered novel low-dimensional this field.
