Integrable Tunable Laser Assembly is a laser module designed to be easily integrated into optical or photonic systems while allowing the emission wavelength to be tuned over a specified range. It typically combines a tunable laser source with control electronics and optical components in a compact package. These assemblies are used in applications such as optical communications, sensing, and photonic integrated circuits.
We demonstrate a wavelength tunable Distributed-Vibration-Sensing over PON scheme using low-cost ITLA and Enhanced-Scattering-Fibers. Vibrations at frequency grids of 193.40THz and194.60THz in a PON with 1×16 splitter and 21 km feeder-fiber were successfully detected.
