The special structure of PCF and the special manufacturing process, such as tube-rod stacking method, allow for a greater degree of freedom in the design and manufacture of PCF. Based on various optical fibre designs, PCF can exhibit one or more of the following characteristics: endless single-mode transmission, ultra-large single mode field diameter, adjustable dispersion in a wide range, ultra-high nonlinear coefficient, excellent birefringence, and hollow waveguide transmission. Compared to ordinary optical fibres, these distinctive and excellent properties give PCF unparalleled advantages in supercontinuum sources, optical fibre lasers, amplifiers, high-energy laser transmission, and gas/liquid sensors.
As a world-leading supplier of communication fibres, YOFC is committed to the research and development of this new series of optical fibres. Leveraging synthetic raw materials, PCVD process, and unconventional doped fibre preform manufacturing process, combined with theoretical simulation calculations, YOFC has developed a range of PCF products tailored for various applications.
