Polymer optical fiber sensor side-pumped with polymer clad doped lasing compounds

الملخص EN

Optical fibers were produced by the system manufactured for this purpose and then, PMMA core of polymer optical fiber (POF) and PMMA doped Rhodamine B (RhB) claddings were studied and determine their UV–vis absorption and emission.

The study adopted the mechanism of lateral pumping of the product polymer optical fiber by using laser with 404 nm excitation to study optical specifications of the factory fiber.

It was noted that there were blue shift in maximum peak wavelength in absorption and fluorescence from the doped polymer before use it as clad.

The obtained results by using the doping polymer with (RhB) for clad the amplified spontaneous emission ASE seems in fluorescence study.

The side excitation shows that there were no an overlap between the excitation laser source and the RhB molecule fluorescence.

The results indicate that POF can be a strong candidate for the development of optical fiber sensors.
