Abstract: The present relates to a spatially modulated cladding mode stripper and to an optical fiber comprising a spatially modulated cladding mode stripper. The spatially modulated cladding mode stripper comprises a series of alternating high cladding light extracting regions and low cladding light extracting regions located along a portion of a cladding to modulate extracting of cladding light therefrom.

Abstract: An electric vehicle supply equipment (EVSE) having ability to charge electric vehicle from indoor located 208-240V outlets. The EVSE comprises a flattened armored cable to securely transmit electrical power to outdoor location from indoor located electrical source. In the preferred embodiment, the flattened armored section acts as EVSE anchoring system which providing ease of installation when temporary electric vehicle recharging is required. The EVSE has ability to disconnect electrical power passing through the flat armored cable in case of non proper conditions or if any electrical hazard occurs. A further embodiment comprises a flexible version of flat cable. To enhance its electrical safety, flat wire conductor comprising damage sensor is used to improve the electrical safety. The EVSE may validate flat wire physical integrity before applying electrical power to the flattened flexible cable.

Abstract: There is provided a multi-cavity optical filter providing a substantially parabolic group delay response with a negative second derivative over a wide bandwidth. The optical filter is made by cascading a plurality of reflective elements wherein a highly reflective element is not positioned at the end of the cascade but is rather inserted between elements of lower reflectivity. The resulting filter has a substantially parabolic group delay response with a negative second derivative when light is injected in one direction of light injection.

Abstract: A multi-wavelength laser source is provided including a pump laser unit, a gain section and an output. The pump laser unit generates an energy signal, which is applied to the gain section. The gain section includes a gain medium with having a superstructure grating forming a distributed Fabry-Perot-like structure. The superstructure grating causes a multi-wavelength laser signal to be generated when the energy signal is applied to the gain medium. The multi-wavelength laser signal is then released at the output.

Abstract: A device for tailoring the chromatic dispersion of a multi-channel light signal is proposed. The device includes at least two waveguides coupled in a cascade, each provided with a spatially distributed optical filter. The group delay response of the filters is designed so that the group delay of each channel of the light signal can be tuned independently of the others, and an appropriate tuning mechanism is provided for this purpose. The device may advantageously be used as a flexible dispersion compensator.
