All-optical, all-fiber, thermal conductivity sensor for identificationand characterization of fluids

This paper presents a miniature, all-optical, thermal conductivity fiber-optic sensor, which can be applied to various fluid composition identification situations. The sensor is composed of a short section of highly absorbing fiber, which is configured as a Fabry-Perot interferometer. A Read More …

All-fiber micromachined microcell

This Letter presents an open-path, all-fiber microcell and a micromachining method for its production. The proposed micromachining method utilizes the selective etching of a purposely designed phosphorus-doped fiber that is spliced in between two standard lead-in fibers. Microcells with various Read More …

Miniature micro-wire based optical fiber-field access device

This paper presents an optical fiber-field access device suitable for use in different in-line fiber-optics systems and fiber-based photonics components. The proposed device u tilizes a thin silica micro-wire positioned in-between two lead-in single mode fibers. The thin micro-wire acts Read More …

Nanowire-based refractive index sensor on the tip of an optical fiber

This letter presents a refractive index sensor created at the tip of an optical fiber that utilizes silica nanowire within a radius of between 225 nm and 600 nm, as a sensing element. Sensitivity in excess of 800 nm/RIU was Read More …
