There is another class of fibers that use a two-dimensional transverse periodicity [51, 52]. These fibers are called photonic crystal fibers (PCFs) or holey fibers (HFs). PCFs are classified into two ...

Photonic Crystal Fibers (PCFs) represent one of the most successful and impactful applications of photonic crystals. These specialized optical fibers incorporate a microstructured arrangement of ...

The year 2009 marks the tenth anniversary of the first report of white-light supercontinuum generation in photonic crystal fibre ... microstructure optical fibers with anomalous dispersion ...

A crystal radio is basically a high Q resonator tied to an antenna and an envelope detector. These days the envelope detector is a point contact diode such as a 1N34 Germanium diode. The resonant ...

It’s a non-linear optical process that’s usually accomplished with expensive bits of kit, like photonic crystal ... that a simple silica glass single-mode fiber could be used to produce ...

Specialty optical fiber is modified, usually by doping, for a specialized function. It consists of one or more transparent fibers enclosed in a protective covering. Optical fiber should not be ...

When it comes to your digestive system, fiber is highly important. It helps to lower cholesterol and prevents constipation and can even help with weight loss. With the right amount of fiber your ...

The SUTD team fabricated their 3D photonic crystal by drawing upon multiple disciplines like material science, optics, and fabrication techniques. To print the crystals, the team turned to two-photon ...

While many people don’t get enough fiber, you could actually get too much, especially if you increase your intake too quickly. See a doctor if you’re experiencing nausea, vomiting, a high ...

Not all polymers are good for making fabric, though. The polymers that are the building blocks of fabrics are special because they clump together to form long fibers. For thousands of years, people ...

Billy Crystal and his wife, Janice, have been married for more than 50 years Kaitlin Stevens is a contributing writer at PEOPLE. She has been working at PEOPLE since 2022. Her work has also ...
