Dual fiber helical long period gratings
Paper 7212-17 of Conference 7212
Date: Monday, 26 January 2009

OPTO, Session 4: Passive Fiber: 3:50-5:20 pm

Abstract: Long period fiber gratings (LPFGs) couple core and co-propagating cladding modes and play a notable part of photonic technology. We have recently developed a new approach to LPFG fabrication in which optical fibers are uniformly twisted at elevated temperatures to produce double or single helices This approach is is advantageous for sensing and gain-flattening applications because of its robustness, low cost and polarization insensitivity Here we describe a new method for producing twisted LPFGs with offset cores, which allows the use of virtually any conventional or specialty fiber for grating manufacture while providing the flexibility of a custom preform.


PANDA-based chiral in-fiber polarizer
Paper 7212-12 of Conference 7212
Date: Monday, 26 January 2009

OPTO, Session 3: Fiber Devices: 1:30-3:20 pm
Abstract: We demonstrate a chiral in-fiber linear polarizer based on a PANDA PM fiber with <0.5 dB insertion loss, >30dB extinction ratio, >300nm bandwidth and >40dB return loss. The cladding and stress members are etched differentially to produce a highly non-circular cross section so that birefringence of the order of 10-2 can be achieved when the fiber is drawn down to ~2?m. An accelerated twist converts the fast/slow linearly polarization component into elliptical polarization with the same/opposite handedness as the fiber twist and scatters polarized light with the handedness of the fiber. This all-glass, scattering polarizer is suitable for high-power applications.


Chiral fiber optical isolator
Paper 7195-10 of Conference 7195
Date: Monday, 26 January 2009

LASE, Session 4: Components: 1:30-3 pm
Abstract: We present a theory of an in-fiber chiral optical isolator based on the chiral fiber polarizer technology utilizing helical microforming of glass fibers. The isolator will be fabricated from a special preform, which is passed through a miniature heat zone as it is drawn and twisted. The performance of the isolator based on a novel non-reciprocal polarization converter, which passes forward traveling left circularly polarized (LCP) light as LCP, while converting backward propagating LCP to right circularly polarized (RCP) light.


"Vanishing-core" tapered coupler for interconnect applications
Paper 7221-15 of Conference 7221
Date: Monday, 26 January 2009

OPTO, Session 4: Optical Interconnects: Technologies: 4-5:40 pm

Abstract: The "vanishing-core" tapered coupler is an all-fiber device that efficiently couples light between a standard low numerical aperture (NA) waveguide, such as a standard silica fiber, and a high numerical aperture waveguide or device with a dissimilar mode field profile, such as a planar waveguide, laser diode or laser diode device. This lens-less, low-insertion-loss solution obviates the need for an air gap between coupled components, thereby enabling the use of index matching compounds. The all-fiber design also facilitates polarization selective and polarizing coupling and the pursuit of very high density, passively aligned interconnects.
