摘要： Ring and linear cavity, fiber optic laser systems are disclosed, employing non-invasive fiber optic amplification technology. A channel overlay waveguide is employed for amplification of optical energy evanescently coupled to the overlay waveguide from the fiber optic. One of two amplification methods can be employed. The first involves inducing stimulated emission with the overlay waveguide and the second uses a second order, non-linear frequency conversion to down-convert a high-power, short-wavelength pump signal into the waveguide to amplify the optical energy coupled thereto. Amplification of optical energy in the channel overlay waveguide can be established within a single beat length of evanescent removal to evanescent return of the optical energy to the fiber optic. Intra-cavity elements can be employed to effect, e.g., wavelength selection, optical isolation, or modulation of the resultant, optical signal propagating in the fiber optic.

摘要： A compound waveguide device having a channel waveguide in optical proximity to an elongate waveguide propagating an optical signal therein is disclosed. The channel waveguide includes a coupling surface through which optical energy is evanescently coupled to or from the optical signal propagating in the elongate waveguide. The channel waveguide is shaped to confine distribution of the optical energy therein along axes transverse to the axis of propagation of the optical energy. Transverse diffraction of the optical energy within the channel waveguide is thereby limited. In one embodiment, the elongate waveguide is a side-polished fiber optic waveguide. Electro-optic control of the compound waveguide is disclosed, as are bandstop, bandpass and detection configurations thereof.

摘要： Controllable fiber optic attenuators and attenuation systems (100) are disclosed for controllably extracting optical energy from a fiber optic (30), and therefore attenuating the optical signal being transmitted through the fiber optic (30). In one aspect, material is removed from a portion of the optical fiber (30), thereby exposing a surface through which optical energy can be extracted. A controllable material is formed over the surface for controllably extracting optical energy according to a changeable stimulus applied thereto, which affects the refractive index thereof. In an improved embodiment, a controllable material is formed over the exposed surface for controlling the amount of optical energy extracted from the fiber optic, and a bulk material is formed over the controllable material, into which the extracted optical energy is radiated.

In one aspect, material is removed from a portion of the fiber optic, thereby exposing a surface through which optical energy can be extracted. The portion of the fiber is suspended between two support points, and a controllable material is formed over the surface for controllably extracting optical energy according to a changeable stimulus applied thereto, which affects the refractive index thereof. In one embodiment, the changeable stimulus is temperature, and a controllable heating/cooling source can be provided in the attenuator for control of the attenuation. The limited amount of thermal contact between the suspended, side-polished portion of the fiber optic and the controllable material to surrounding structures offers a more predictable response, and improved response time. The controllable material, in one embodiment, may be a dispersion controlled (e.g., matched) polymer, offering uniform spectral characteristics of attenuation across a wavelength band of interest.

In one aspect, material is removed from a portion of the fiber optic, thereby exposing a surface through which optical energy can be extracted. A controllable material is formed over the surface for controllably extracting optical energy according to a changeable stimulus applied thereto, which affects the refractive index thereof. In an improved embodiment, a controllable material is formed over the exposed surface for controlling the amount of optical energy extracted from the fiber optic, and a bulk material is formed over the controllable material, into which the extracted optical energy is radiated. The controllable material has a controllable index of refraction approximately matching the index of refraction of the cladding of the fiber optic, and the bulk material formed over the controllable material has a fixed index of refraction higher than the effective mode index of refraction of the fiber optic. This cladding-driven design varies the effective optical thickness of the controllable material, and therefore effects a controllable attenuation of the optical signal being transmitted in the fiber optic. Attenuation systems including these controllable attenuators, as well as control and sense sub-systems, are also disclosed.
