Filtering of optical fibers and other related devices. High-energy methods for depositing thin films directly onto the ends of optical fibers can be used to produce high-quality, high-performance filters in quantity at a reasonable cost. These high-quality filters provide the high performance needed for many demanding applications and often eliminate the need for filters applied to wafers or expanded-beam filtering techniques. Having high-quality filters applied directly to optical fiber and faces permits production of high-performance, micro-sized devices that incorporate optical filters. Devices in which these filters may be used include spectroscopic applications including those using fiber optic probes, wavelength division multiplexing, telecommunications, general fiber optic sensor usage, photonic computing, photonic amplifiers, pump blocking and a variety of laser devices.
An optical fiber assembly, comprising a fiber segment having a complex contoured end face and an integral filter adhered to and covering at least a first portion of said end face, said filter comprising metal oxide.
An optical fiber assembly comprising a fiber segment and at least one integral rugate filter adhering to an end face of said fiber segment, said filter having a packing density of at least ninety-five percent.
An optical fiber assembly, comprising a short optical fiber segment, an integral rugate filter adhering to an end face of said segment, and a longer optical fiber butted end to end to said segment.
An optical fiber assembly, comprising an optical fiber segment having an end face and at least one rugate filter comprising metal oxide adhering to the end face.
An optical fiber assembly, comprising:
An optical fiber assembly, comprising a plurality of optical fiber segments butted to each other end to end, wherein at least one of the segments includes an integral rugate filter adhered to an end face of the segment.
An optical fiber assembly for transmitting monochromatic light for light based characterization, comprising:
A fiber optic assembly, comprising:
An optical fiber assembly, comprising an optical fiber segment having a complex contoured end face and an opposite end face, an integral filter adhering to one of the end faces of the optical fiber segment and covering at least a portion of said end face, and a longer fiber butted end-to-end to said optical fiber segment.
