When using waveform tomography to perform high-resolution imaging of a medium, it is vital to calculate the sensitivity in order to describe how well a model fits a given set of data and how the sensitivity changes with the spatial distribution of the he
We have demonstrated a proof-of-principle experiment of reference-frame-independent phase coding quantum key distribution (RFI-QKD) over an 80-km optical fiber. After considering the finite-key bound, we still achieve a distance of 50 km. In this scenario, the phases of the basis states are...
In order to match the fiber grating demodulation system for fiber Bragg grating to achieve weak signal detection and processing, the application of a weak optical signal detection theory, based on the design of a high signal to noise ratio high detection accuracy of the demodulation circuit, the...
Photodiodes are faster and more complex than normal PN junction diodes and hence are frequently used for lighting regulation and optical communication. Stay tuned to BYJU’S to know more about the modern-day uses of photodiodes with interesting video lectures and fall in love with learning!
Optical time domain reflectometry (OTDR) is well established to measure the transmission characteristics (attenuation, splice loss, fault location) of optical-fibre communication channels. A short light-pulse (typical duration 1 碌s) is launched into one end of the fibre and the resulting ...
