Abstract: A device used for dispersion compensation of a plurality of optical signals passing through an optical transmission line. The device includes a photosensitive optical fiber including a long length, chirped Bragg grating providing dispersion compensation over a wide bandwidth of optical signals. The long length chirped Bragg grating has a reflection bandwidth greater than about 25nm, and further has reduced distortion at a bit rate of about 10 -9 . This reduced distortion leads to a power penalty of less than 3 dB during less than 25 nm stepwise changes in wavelength of the plurality of optical signals across the wide bandwidth. The device provides a dispersion greater than about 100 ps/nm in a optical transmission line operating at 10 Gbit/s.

Abstract: The present invention relates to an optical based bending sensor. In particular, the present invention relates to a fibre-based bending sensor for the determination of the direction and the amplitude of a bend. The present invention further relates to fibre-based bending sensors using long-period fibre gratings (LPG), in which the intrinsic properties of the fibre and the bend sensitivity of LPG is utilised. In a preferred embodiment, the connection between the Core Concentricity Error (CCE) of the fibre and the LPG in the asymmetric bend behaviour results in coupling resonance between the core and the cladding modes. Thereby a relative splitting of transmission peaks in the spectrum of the LPG is induced, which is used to determine the bending amplitude and direction.

Abstract: An amplitude mask, and an apparatus and method for manufacturing a long period grating filter using the same, are provided. When a long period grating is manufactured by selectively passing laser light to an optical fiber, the amplitude mask periodically passes laser light to the optical fiber. The amplitude mask includes two masks (300) having periodically alternating pass areas (308) for passing the laser light and nonpass areas for preventing passing of the laser light, wherein the two masks (300) are continuously rotated in opposite directions. The period of the pass area (308) thus continuously changes. In this mask, two masks (300) each having a predetermined period are rotated in opposite directions, to thus provide an amplitude mask period depending on the angle of rotation ( alpha ). Thus, the period of the amplitude mask can be continuously changed.

Abstract: This invention relates to a method and a system for writing fiber Bragg gratings (FBG) having apodized spectrum ("apodized FBG") on optical fibers. An amplitude modulation mask is placed between a focusing cylindrical lens and the optical fiber. By reducing the distance between the amplitude mask and the fiber, the present invention can minimize diffraction effects that may be induced by long propagation distance of a laser beam passing through a small and/or narrow aperture in the amplitude mask. The method and system of the present invention can be applied to write FBG with apodized spectrum with small amplitude mask to achieve full width at half maximum (FWHM) bandwidth (BW) wider than 1.2 nm and to achieve side lobe suppression ratio (SLSR) as high as 30 dB. These method and system generally increase the laser power efficiency of the laser used in FBG inscription and optimizes the grating index modulation profile.
