摘要： A side-polished fiber/overlay waveguide architecture and process for non-invasively implementing an optical amplifier are provided for an optical communications system. A "channel" overlay waveguide is employed to constrain for amplification optical energy evanescently coupled to the overlay waveguide from the side-polished optical fiber. The overlay waveguide exhibits a non-linear response of second order, and non-linear frequency conversion is employed to down-convert a high-power, short-wavelength pump signal into the waveguide to amplify the optical energy coupled thereto. The channel overlay waveguide is dimensioned to allow for phase matching between highest order modes of the optical signal within the side-polished fiber optic and the pump signal provided to the channel overlay waveguide. A low-index matching layer is disposed between the channel overlay waveguide and the side-polished fiber optic to facilitate phase matching of the propagation modes. Amplification of optical energy in the channel overlay waveguide is established within a single beat length of evanescent removal to evanescent return of the optical energy to the side-polished fiber optic.

摘要： An optical amplifier with integrated optical waveguide, pump source and other, optional components for amplifying an input optical signal coupled from a fiber optic. The amplifier includes a housing having these components mounted therein, and appropriate optics for coupling the input and output optical signals to and from the appropriate ports, and for carrying an optical pump signal from its source to the waveguide. The optical waveguide disclosed is a channel waveguide amplification chip, having a relatively small size; and the pump source disclosed is a laser diode capable of generating the optical pump signal internal to the housing with only electrical (e.g., power) signals applied thereto from outside of the housing. Other optional components may be provided for cooperative optical processing in the amplifier housing. The disclosed optical amplifier offers size and cost advantages over other known systems.

摘要： An optical waveguide, radiation emitting device employing the same, and process for fabricating the radiation emitting device are provided. The optical waveguide has a core fabricated of a first material with a first index of refraction and cladding surrounding the core fabricated of a second material with a second index of refraction. The core is an active material which emits radiation at a desired wavelength when pumped with radiation of a predetermined wavelength, and the first material and second material are dissimilar materials, having been separately fabricated and subsequently physically assembled as the waveguide. The light emitting device employing the optical waveguide is configured either as an amplified spontaneous emission (ASE) source or laser source employing appropriate reflective materials at the ends of the optical waveguide.

摘要： A side-polished fiber/overlay waveguide architecture and process for non-invasively implementing an optical amplifier are provided for an optical communications system. A "channel" overlay waveguide is employed to constrain for amplification optical energy evanescently coupled to the overlay waveguide from the side-polished optical fiber. 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 side-polished fiber optic.
