Researchers from the School of Physics at Mohammed VI Polytechnic University (UM6P) have developed a new method that combines the properties of two-dimensional (2D) materials, such as molybdenum disulfide (MoS\u2082), with optical fibers. This approach could contribute to advances in communication technologies, quantum optics, and neuroscience.<\/p>\n
Their study, published in the Journal of Physics D, focuses on growing single layers of MoS\u2082 directly on optical fibers using a process called atmospheric pressure chemical vapor deposition (CVD). The researchers compared how the material behaves on optical fibers versus traditional flat surfaces, such as silicon oxide (SiO\u2082).<\/p>\n
Using techniques such as Raman spectroscopy and photoluminescence measurements, they observed a shift in the optical signals from MoS\u2082 when placed on curved optical fibers. This shift is due to mechanical strain caused by the fiber\u2019s shape, which affects the material’s electronic properties.<\/p>\n
The team suggests that these MoS\u2082-coated optical fibers could be used for both optical and electrical sensing. This means they could detect signals not only through light but also through electrical responses, which may help study brain activity and develop brain-machine interfaces, further solidifying the UM6P School of Physics as a leading institution in innovative scientific research in Morocco.<\/p>\n
This work opens up new possibilities for building flexible and multi-functional systems in optics, sensing, neuroscience, and quantum research.<\/p>\n
