Advanced Optical Materials, Volume 11, Issue 12, June 19, 2023., 2023 Synthesis of silicon oxynitride‐doped silicon is demonstrated for the first time with a control in the refractive indices. This technique with a single deposition step also yields high reflective Bragg gratings (BGs) on bulk substrates as well as on the tip of optical fibers.

Broadband Nonlinear Photonics in Zeolite‐Based Selenium Chains
Advanced Photonics Research, Volume 4, Issue 6, June 2023., 2023 Se nanochains are successfully prepared by trapping Se species in the circular 1D channel of AlPO4‐5 (AFI) crystal. Subsequently, the Se@AFI composite materials are used as a broadband saturable absorber to generate the stable mode‐locking pulse in the fiber laser at 1564 and 1043 nm.

Jurnal Teknologi, 2016 An amplification for single pass operation was demonstrated by using Zirconia-based erbium-doped fiber (Zr-EDF). 1 m is the optimum length due to overall high gain and minimal noise figure from 1520 nm to 1620 nm. The highest gain is 28.62 dB at 1555 nm with the input signal and pump power are fixed at -30 dBm and 130 mW, respectively. At input signal -
