Latest Patents
Pearsall's latest patents include a method of making a fiber having low loss at 1385 nm by cladding a VAD. This innovation involves creating a singlemode optical fiber with very low loss at 1385 nm, which is crucial for efficient optical transmission. The process includes fabricating a core rod using vapor axial deposition, dehydrating it in a chlorine- or fluorine-containing atmosphere, and consolidating it in a helium atmosphere. The resulting fiber's loss at 1385 nm is reduced to a level that is less than its loss at 1310 nm, making the entire wavelength region from 1200-1600 nm suitable for optical transmission. This advancement allows wave-division-multiplex systems to transmit optical signals over distances greater than 10 km in the wavelength region between 1360 nm and 1430 nm.
Another patent focuses on a method for stretching refractory bodies. This method involves exposing a refractory body to a high-temperature oxygen-containing plasma while applying a drawing force to elongate the body. The technique is particularly beneficial for manufacturing optical fiber core rods with low optical attenuation.
