摘要： Light is coupled between two or more layers of light guides in an optical chip at a desired connection point by interconnecting the light guides of each layer at the desired connection point using an “optical via”. The optical via is located between the light guides being connected in the layer that otherwise operates to insulate the layers containing the light guides. Such an optical via may be made of a material that has an index of refraction that is conducive to optically coupling between the light guides. The geometry of the interconnection at the optical via is arranged so that the light traveling in one of the light guides to reimage itself across the optical via and continue traveling in the other of the light guides.

摘要： It is possible to perform reset free operation in devices having polarization state controllers by employing specific sequences of phase shifters and couplers. In particular, sequences comprising a coupler/phase shifter/coupler or phase shifter/coupler/phase shifter formed in, for example, a semiconductor substrate, e.g. silicon substrate, are used to form the polarization state controller. A sequence functions as a quarter wave plate equivalent while two combined sequences function as a half wave plate. Control of the couplers and phase shifters of these sequences yield reset free operation.

摘要： A semiconductor waveguide includes a section containing free charge, either electrons or holes, which can be steered into or removed from the path of the beam under the control of electrical signals. The mobile charges come from a potential well which may be either filled or depleted under electrical control. When the well is filled, the charges speed the beam propagation, introducing a phase change. When the well is emptied the beam propagates with extra delay. The phase shifter allows very high speed modulation of the beam using low voltage and low power electronics. The device can be created using standard silicon processing techniques, and integrated with other optical components such as splitters and combiners to create amplitude modulators, attenuators and other optical devices.

For example, a sequence functions as a quarter wave plate equivalent while two combined sequences function as a half wave plate. Moreover, sequences functioning as wave plates more general than quarter wave plates are advantageously employed. Control of the couplers and phase shifters of these sequences yield reset free or reset free, fully deterministic operation.

摘要： A liquid crystal polarization rotator device is able to rotate polarization fast enough to compensate polarization mode dispersion. The amount or degree of rotation is rapidly reconfigurable. The device includes a cavity filled with a nematic liquid crystal material. The cavity has electrodes on a first face, e.g., a first substrate, and electrodes on a second face, e.g., a second substrate, opposite the first face. The electrodes are shaped and positioned to produce an electric field across the cavity capable of rotating the alignment direction of the molecules of the liquid crystal material in the cavity. The electrodes are patterned on the ends of optical fibers. Aligning and positioning of the electrodes on the ends of the optical fibers with a predetermined spacing forms the cavity that is filled with the nematic liquid crystal material. The filled cavity is a so-called liquid crystal microcell wave plate. A control system is used to control the “rapid” rotation of the alignment direction of the molecules of the liquid crystal material. The control system receives data regarding the polarization of light entering or leaving the microcell and adjusts the direction of the electric field also using trigger pulses such as to rotate the nematic liquid crystal material molecules by a first predetermined number of degrees greater than a second desired number of degrees of rotation. Then, the trigger pulses for the electric field are stopped after the molecules have rotated by the second desired number of degrees. In this manner, the molecules rotate by the second desired number of degrees much faster than if a pulse had been applied with the same speed to rotate them by the second desired number of degrees in he first place.
