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： Controllable fiber optic attenuators and attenuation systems are disclosed for controllably extracting optical energy from a fiber optic, and therefore attenuating the optical signal being transmitted through the fiber optic. 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.
