AbstractData rates in optical fiber networks have increased exponentially over the past decades and core-networks are expected to operate in the peta-bit-per-second regime by 2030. As current single-mode fiber-based transmission systems are reaching their capacity limits, space-division multiplexing has been investigated as a means to increase the per-fiber capacity. Of all space-division multiplexing fibers proposed to date, multi-mode fibers have the highest spatial channel density, as signals traveling in orthogonal fiber modes share the same fiber-core. By combining a high mode-count multi-mode fiber with wideband wavelength-division multiplexing, we report a peta-bit-per-second class transmission demonstration in multi-mode fibers. This was enabled by combining three key technologies: a wideband optical comb-based transmitter to generate highly spectral efficient 64-quadrature-amplitude modulated signals between 1528 nm and 1610 nm wavelength, a broadband mode-multiplexer, based on multi-plane light conversion, and a 15-mode multi-mode fiber with optimized transmission characteristics for wideband operation.

Stable Performance

Here we report on a miniaturized optical interferometer in one fiber based on two mismatched nodes. The all-fiber structure shows stable performance of temperature and humidity sensing. For temperature sensing in large ranges, from 40 to 100 °C, the sensor has a sensitivity of 0.24 dB/°C, and the adjusted R-squared value of fitting result reaches 0.99461 which shows a reliable sensing result. With carbon nanotubes coating the surface of the fiber, the temperature sensitivity is enhanced from 0.24561 to 1.65282 dB/°C in a small region, and the performance of humidity sensing becomes more linear and applicable. The adjusted R-squared value of the linear fitting line for humidity sensing shows a dramatic increase from 0.71731 to 0.92278 after carbon nanotube coating, and the humidity sensitivity presents 0.02571 nm/%RH.

An extrinsic Fabry-Perot (F-P) interferometric (EFPI) sensor by using simple etching and fusing method is proposed and demonstrated. The cavity is formed by wet chemical etching of multi-mode fiber (MMF) end face in hydrofluoric acid solutions, and then it is fused to the end of a single-mode fiber (SMF) to form an extrinsic F-P structure. The strain and temperature of EFPI sensor are studied experimentally. The experimental results show that the interference wavelength becomes 2.648nm longer while the strain increases from 0N to 637N, and the strain sensitivity is about 0.004nm/N, and linearity is 0.999. The interference wavelength becomes 0.032nm shorter while the temperature increases from 20°C to 100°C. This kind of sensor has the many advantages of easy fabrication, good reliability, high-repetition, small size, low cost and mass-production, which offers great prospect for sensing applications.
