摘要： Optical waveguides prepared by irradiating selected regions of positive photochromic polymeric materials with actinic radiation are disclosed. The photochromic materials undergo an irreversible photochemical change which results in an increase in the refractive index of light-exposed regions. In addition, the materials exhibit negligible second-order polarizability prior to exposure and excellent nonlinear optical properties after exposure and polarization. Thus, the exposed regions are particularly useful as the core in active waveguides for use in second-order nonlinear optical applications, as well as the core in passive waveguides. In addition, a simple two step process is disclosed for forming optical waveguides from the positive photochromic polymers. Optical structures, such as optical integrated circuits, and optical devices which incorporate the waveguides are also disclosed. The optical devices may be used as optical modulators, filters, attenuators, amplifiers, frequency converters, and electric field sensors, as well as in other nonlinear optical applications.

摘要： An optical channel waveguide amplifier and fabrication process are provided for an optical communications system. The amplifier employs an optical waveguide having a core of active material exhibiting optical fluorescence when stimulated. The core has a propagation axis extending from an input surface to an output surface. The input surface intersects the propagation axis at a non-orthogonal angle (e.g., 45°). A cladding at least partially surrounds the core, and a coating is provided over the angled input surface of the core. The coating is anti-reflective of the optical signal, input at a predetermined signal wavelength, and is highly reflective of the pump, input at a predetermined pump wavelength. A prism, index-matched to the core, is secured to the angled face of the optical waveguide so that the input signal may be focused into the core through the prism and the coating collinearly with the axis of propagation, while the pump is reflected into the core off the coating at the angled input surface from an angle to the axis of propagation. The optical signal undergoes amplification within the core by stimulated emissions of the active material driven by the pump.

摘要： Fiber optic communication links are disclosed, employing non-invasive fiber optic amplification technology. An amplifier stage is provided having a plurality of signal paths into which differing wavelength windows of an input optical signal are demultiplexed. At least one of the paths (e.g., 1310 nm) includes a fiber optic and an associated fiber optic amplifier. 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. Dense wavelength division multiplexing (DWDM) of the 1550 nm and 1310 nm wavelength windows is therefore provided over a single 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.
