摘要： An chiral optical fiber polarizer is provided that is capable of being fabricated in-line along a conventional polarization maintaining fiber, preferably one which includes at least one structure element that is external, and parallel, to the fiber's core. The novel chiral fiber polarizer is preferably positioned between two unmodified optical fiber portions, and includes a modified central portion with altered fiber cladding interface elements on each side thereof. The modified central portion is of a non-circular cross section, and comprises at least one diameter reduced sub-section operable to allow a light signal of said predefined operation wavelength to propagate substantially in the core and in the at least one external structure element, at least one diameter expanded sub-section operable to allow a light signal to propagate substantially in the core, each sub-section being produced in accordance with a corresponding predefined diameter reduction and expansion profile, where the modified central portion is further configured in accordance with at least one helical pitch profile that is operable to, upon receiving a light signal with a first and second linear polarization components: convert the first linear polarization component to a first elliptical polarization component while scattering the first elliptical polarization component, and convert the second linear polarization component to a second elliptical polarization component, transmit therethrough, and convert back to the second linear polarization component prior to exit therefrom. The inventive polarizer also substantially eliminates the possibility of an undesirable SBS effect.

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 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： An optical fiber coupler capable of providing a low loss, high coupling coefficient interface between conventional optical fibers and optical waveguide devices is provided. The novel coupler, which may be polarization maintaining, if a polarization maintaining preform is used in its fabrication includes a core, a cladding, a first end for interfacing with an optical fiber and a second end for interfacing with an optical waveguide device. The sizes of the core and cladding are gradually reduced from the first end to the second end in accordance with a predetermined reduction profile. Various parameters, such as refractive indices and sizes of the core and cladding and the reduction profile are selected to produce a low numerical aperture at the first end and a high numerical aperture at the second end, while advantageously minimizing insertion loss and maximizing the coupling coefficient at each end. In another embodiment, the novel coupler includes a secondary cladding which is also reduced between the first and second ends to improve the strength of the coupler structure at the second end. In yet another embodiment, one or two novel couplers are formed along with a chiral fiber based optical waveguide device as a single continuous element. The optical fiber preform used to fabricate the novel optical fiber coupler can be etched prior to fabrication to facilitate application of the reduction profile.
