摘要： We propose a dynamically tunable electro-optic cladding using our proprietary electro-optic material, applied to various circular and planar wave-guides along with specific electrode configuration and excitation electric field format appropriate to that material. Based on the evanescent field coupling phenomena, the proposed device may be used in variable optical attenuators, tunable filters and couplers, etc. Different design of applied electrodes and optical properties of controllable refractive index materials allow polarization dependent or independent, as well as direct or inverse operation regimes of proposed devices.

摘要： A polarization insensitive optical attenuator is disclosed. Three birefringent wedges are disposed along an optical path with their respective optical axes aligned. The apex angle of the second wedge equals the sum the apex angles of the first and third wedges. A Faraday rotator is disposed along the optical path between the first and the second wedge. A reciprocal rotator is disposed along the optical path adjacent to the Faraday rotator. An optical signal transmitted through the attenuator may be selectively divided into three spatially separate output rays while maintaining a predetermined attenuation or substantially complete isolation from reflected signals. Adjustment of the optical rotation angles allows the attenuator to be easily adapted to a wide variety of industrial and commercial laser applications.

摘要： An optical wave power control device and method enables signal control, such as modulation transferring and switching, to be effected with the application of very low power to a controller which is in optical communication with a recirculating mode resonator and an optical propagation element. The propagation element is configured such that is in power communication with a high Q volumetric resonator. Power of a chosen resonant wavelength is coupled into said resonator, where it circulates with very low loss and returns energy to the propagation element. By introducing a control signal into the controller, the propagated power can be varied between substantially full and substantially zero amplitudes. Loss factors can be maintained such that said resonator is overcoupled, i.e. parasitic losses are less than coupling losses, and a critical coupling condition exists in which a small swing in the controller causes a disproportionate change in the optical output signal. The controller is preferably effectuated by an interferometer in the optical path of said resonator and a control signal, which can be an applied voltage, current or optical signal.

摘要： An optical device which can be used as a Faraday rotator which can provide an arbitrary Faraday rotation angle in accordance with a positional condition. The optical device includes first and second ports, magneto-optical crystal, and a unit for applying a magnetic field to the magneto-optical crystal. The first port is positioned in a first region while the second port is positioned in a second region. The first and second ports are optically coupled by a light beam. The magneto-optical crystal is provided such that the light beam may pass therethrough. The unit for applying applies a magnetic field to the magneto-optical crystal so that magnetization of the magneto-optical crystal may have a given distribution in a plane substantially perpendicular to the light beam. Since the magnetization of the magneto-optical crystal has the given distribution, whether the first port is at a certain position or at another position, the Faraday rotation angle provided to the light beam is different in accordance with the distribution. Accordingly, an arbitrary Faraday rotation angle can be provided in accordance with a positional condition.

摘要： An optical power regulator employs a variable optical attenuator having a first birefringent element that spatially separates the input optical beam into two orthogonally-polarized beams. Both beams pass through a polarization modulator (e.g., a liquid crystal material) that rotates their polarizations to an extent determined by the control voltage applied across the polarization modulator. A final birefringent element spatially separates both beams exiting the polarization modulator into two pairs of orthogonally-polarized beams (i.e., two horizontally-polarized and two vertically-polarized components). The thicknesses and optical properties of the birefringent elements are selected so that two of the four beams are combined by the final birefringent element to exit at the output port of the regulator, while the remaining two beams are blocked. As a result, the degree of attenuation is determined by the degree of polarization rotation by the polarization modulator, which in turn is a function of the control voltage applied to the polarization modulator. Preferably, the liquid crystal material used in the polarization modulator has a high optical birefringence and a low dielectric anisotropy, which results in a relatively shallow attenuation curve as a function of applied voltage. The intensity of the optical signal is measured by a photodetector and used by a controller to output the control voltage applied to the liquid crystal material to maintain a desired optical power level at the output port of the regulator.
