Abstract: A burner for submerged combustion melting that mixes a first gas and a second gas inside the burner and emits the mixed gas through a nozzle for combustion below the surface of the material being melted. The burner includes a hollow tube and a static mixer inside the tube that mixes the first gas and the second gas as they travel through the tube. The mixed first and second gas exits a nozzle on a top end of the tube and is ignited to generate a flame below the surface of the material being melted, which may be a glass material.

Abstract: Multimode optical fiber systems with adjustable chromatic modal dispersion compensation are disclosed, wherein the system includes a VCSEL light source and primary and secondary optically coupled multimode optical fibers. Because the VCSEL light source has a wavelength spectrum that radially varies, its use with the primary multimode optical fiber creates chromatic modal dispersion that reduces bandwidth. The compensating multimode optical fiber is designed to have a difference in alpha parameter relative to the primary multimode optical fiber of −0.1≦Δα≦−0.9. This serves to create a modal delay opposite to the chromatic modal dispersion. The compensation is achieved by using a select length of the compensating multimode optical fiber optically coupled to an output end of the primary multimode optical fiber. The compensating multimode optical fiber can be configured to be bend insensitive.
