Abstract: Optical fiber filters and uses thereof are presented. In typical implementations, there is provided a FBG taking deleterious light out of a fiber core without reflecting it into the fiber core. It also allows the unhindered transmission of useful light at a wavelength outside of the spectral band covered by the deleterious light. The filter couples the incoming deleterious light to cladding modes propagating in the opposite direction without coupling the incoming useful light to core or cladding modes propagating in the opposite direction. The filter may for example be useful as a Raman or ASE filter in a laser cavity of other optical devices.

Abstract: A Mach-Zehnder optical modulator with a travelling wave electrode has a signal transmission line conductor (S) carrying an input electrical signal, and two ground transmission line conductors (G1 and G2) providing a return path for the electrical signal. The signal transmission line conductor is positioned between the first and second ground lines, and the first and second optical waveguide branches are positioned between the signal transmission line conductor and the first ground line. The modulator therefore has a GSG structure providing an asymmetrically-loaded configuration.

Abstract: An optical coupling assembly for coupling light from an optical fiber including an angled tip into a planar waveguide via a waveguide coupling element is provided. In one embodiment, the optical fiber extends along the planar waveguide with the angled tip positioned such that light propagating in the optical fiber is coupled by the waveguide coupling element to propagate in the planar waveguide in counter propagation with respect to a fiber propagation direction. In another embodiment, the optical fiber includes a tapered peripheral portion tapering toward the angled tip and is disposed over the planar waveguide with the tapered peripheral portion extending therealong such that light propagating in the optical fiber is coupled to propagate in the planar waveguide with either forward or counter propagation. Embodiments of the present invention may be part of various photonic integrated circuits and may be manufactured more easily than known optical coupling assemblies.

Abstract: A tunable dispersion compensator for the compensation of the chromatic dispersion experienced by a single-channel or multi-channel light signal. The compensator includes a plurality of optical structures such as chirped Bragg gratings or combinations thereof, each having a characteristic dispersion profile. An optical coupling arrangement successively propagates the light signal in each of these structures, so that it accumulates the dispersion compensation effect of each. A tuning device jointly tunes the dispersion profile of each optical structure by applying a same tuning force thereto, preferably a temperature gradient.
