  • Publication number: 20080145693
    Abstract: A heterostructure of multiferroics or magnetoelectrics (ME) was disclosed. The film has both ferromagnetic and ferroelectric properties, as well as magneto-optic (MO) and electro-optic (EO) properties. Oxide buffer layers were employed to allow grown a cracking-free heterostructure a solution coating method.

  • Publication number: 20070285763
    Abstract: The present invention provides a neodymium doped, transparent electro-optic gain ceramic material consisting lead, zirconium, titanium and lanthanum. The electro-optic gain ceramic material either has a linear electro-optic coefficient or a quadratic electro-optic coefficient, which is greater than about 0.3×10?16 m2/V2 for the latter, a propagation loss of less than about 0.3 dB/mm, and an optical gain of great than 2 dB/mm at a wavelength of about 1064 nm while optically pumped by a 2 watts diode laser at a wavelength of 802 nm at 20° C. The present invention also provides electro-optic devices including a neodymium doped, transparent electro-optic gain ceramic material consisting lead, zirconium, titanium and lanthanum. The present invention also provides lossless optical devices and amplifiers with an operating wavelength in the range of 1040 nm to 1100 nm while optically pumped at a wavelength in the range of 794 nm to 810 nm.

  • Publication number: 20040088298
    Abstract: Systems and methods for managing a distributed transaction process include an active transaction manager that manages transactions with an active database, a latent transaction manager that manages transactions with a merge database, a transaction log that reflects the set of transactions in the active database that are not affiliated with the transactions in the merge database, and a merge manager that uses the transaction log to determine whether to transfer control of the merge database to the active transaction manager. Systems and methods may further instruct the active transaction manager to halt transactions with the active database while the merge database is updated to reflect a set of transactions affiliated with the set of transactions in the transaction log, and instruct the active transaction manager to subsequently manage transactions to the active database and the merge database.

  • Publication number: 20040064332
    Abstract: Systems and methods for processing benefits include providing a graphical user interface, such as a web browser, to a benefit recipient for accessing at least account information concerning at least one benefit type. The benefits processing system may receive a request from the benefit recipient through the graphical user interface for displaying the at least account information concerning the at least one benefit type. The benefits processing system may then display the at least account information through the graphical user interface concerning the at least one benefit type.

  • Patent number: 6404538
    Abstract: An optical modulator is provided to control the intensity of a transmitted or reflected light. In a transmission mode, a separator splits arbitrarily polarized light into two polarization rays and one is made to travel a separate path from the other. A recombiner causes the two rays to recombine at an output unless an electro-optic phase retarder changes the polarization of the two rays, in which case, both of them miss the output by an amount which is a function of the voltage on the retarder. A normally-off version with low polarization mode dispersion is obtained by changing the orientation of the recombiner. A normally-on version with low polarization mode dispersion is obtained with a passive polarization direction rotator. Similar results can be obtained in a reflection mode where the input and output are on the same side of the modulator. Versions using a GRIN lens are particularly suited to modulation of light out of and back into fiber-optic cables.
