摘要： A single helix chiral fiber grating of a predetermined grating strength is provided that is operable to control light transmission in a predetermined wavelength range. The novel fiber grating comprises a first optical fiber with a first interface portion at a first end, a second interface portion at a second end, and a middle portion therebetween. The first optical fiber is configured with at least one fiber core, surrounded by a corresponding at least one cladding, with a first longitudinal section disposed within the first interface portion, a second longitudinal section disposed within the second interface portion, and also includes a longitudinal helical section, disposed therebetween within the middle portion, that comprises a longitudinal helix structure of a single predetermined handedness, having a predetermined pitch profile, and having a predetermined helix diameter profile selected and configured to produce the predetermined grating strength. The helical section of the novel fiber grating is preferably produced by placing the first optical fiber, proximal to and parallel with a second fiber (or equivalent elongated member), and longitudinally twisting them together to form a double helix structure. Advantageously, the diameter of the second fiber (or a diameter profile thereof) may be selected to achieve the predetermined helix diameter profile in the helical section of the first fiber. The second fiber may be left proximal to the first fiber after fabrication or removed.

摘要： An optical fiber mode coupling device, capable of being readily connected to a conventional optical fiber with a high degree of ruggedness, is provided. The inventive mode coupling device only allows transmission of at least one supported fiber mode therethrough, and is preferably configured to maximize the coupling, of at least one desired fiber mode, to the at least one supported fiber mode. Advantageously, the inventive mode coupling device is capable of performing the functions of a mode filter for the signal entering its first end, or serving as a mode conditioner for the signal entering its opposite second end. Thus, in one practical application thereof, the novel mode coupling device functions as a mode filter by maximizing the coupling between at least one desired fiber mode of a multi-mode input signal entering the device's first end, and at least one supported mode of the device, to produce an output signal at the device's second end that comprises at least one predetermined fiber mode, corresponding to at least one desired fiber mode. In another practical application thereof, the novel mode coupling device functions as a mode conditioner by maximizing the coupling between an input signal, comprising at least one predetermined fiber mode, that enters the device's second end, and, and at least one supported mode of the device, to produce an output signal at the device's first end that comprises at least one desired fiber mode, corresponding to a conditioned at least one predetermined fiber mode.

摘要： A chiral optical fiber polarizer is provided that is capable of being fabricated in-line along a conventional polarization maintaining fiber having external structural element(s), positioned between two optical fiber portions, and includes a modified central portion with altered fiber cladding interface elements on each side thereof. The modified central portion includes at least one diameter reduced sub-section that allows a light signal to propagate simultaneously in the core and in at least one external structure element, and at least one diameter expanded sub-section that allows the light signal to propagate substantially in the core, where the modified central portion is configured to be operable to serve as a polarizer for light signals with linear polarization components.
