Examining amplification and nonlinear properties of novel Quantum Well Optical Fiber (QWOF) for future photonic communications

In this paper, we propose a novel structure of optical fiber to investigate its amplification and nonlinear properties. We employ both nano and optical fiber technologies in our proposed novel structure so-called Quantum Well Optical Fiber (QWOF) where an InP quantum well exists between the core and inner cladding of proposed QWOF. In the developed model, InP is chosen as a semiconductor dopant to examine its amplification and nonlinear properties. From our experimental results, the proposed QWOF shows its significant amplification properties for wavelength between 1080 nm and 1491 nm. Amplification properties also found in wavelength 906 nm~1044 nm and 1524 nm~1596 nm. Though the exact nonlinear parameter could not be determined, a lower bound of 3.87x10⁶ W^-1/m was calculated for gamma where an effective core area has value 2.27236x10^-11 m².
