Power Flow in Multimode Graded-Index Microstructured Polymer Optical Fibers

“…POF has the benefit of an easy connection and a large core, which could be an economic solution for the in-home network. Different kinds of materials are implemented for POF fabrication, such as polymethyl methacrylate (PMMA) [ 3 , 4 ], polydimethylsiloxane (PDMS) [ 5 , 6 ], polycarbonate (PC) [ 7 , 8 ], polystyrene (PS) [ 9 , 10 ], perfluorinated polymer (commercially known as CYTOP ® (AGC, Inc., Tokyo, Japan) [ 11 , 12 ], cycloolefin polymer (commercially known as ZEONEX ® *ZEON (Corporation, Tokyo, Japan)) [ 13 , 14 ], and cycloolefin copolymer (commercially known as TOPAS ® ) (TOPAS Advanced Polymers, Farmington Hills, MI, USA) [ 15 , 16 ]. The flexibility of POF material allows for the production of POFs with varying specifications or materials to meet the needs of various applications.…”

Avaliação Do Petg Para Utilização Em Embarcações Transparentes

“…Contudo ZUBEL et al, (2016), identifi caram que tanto valores muito altos e muito baixos de preenchimento resultavam na redução de transparência das peças. Os autores justifi caram os resultados citando que quando a taxa de preenchimento era muito baixa, não havia material sufi ciente depositado pelo para preencher todo o volume de impressão exigido.…”

Recent Advances in Fiber Bragg Grating Sensing

“…Over the years, the scientific community has relentlessly pushed the boundaries of FBG technology, leading to a cascade of breakthroughs in sensor design, fabrication techniques, and applications [ 4 , 5 , 6 ]. Our exploration will delve into the innovative strides made in the fabrication of FBGs, from traditional UV-induced gratings [ 7 ] to advanced techniques like femtosecond laser inscription [ 8 , 9 ], offering readers a glimpse into the evolution of the fabrication methodologies that underpin the success of optical fiber sensors.…”
