We propose to design a hybrid neural network and knowledge base automatic classification system which dynamically constructs an optimal decision tree. Our proposed hybrid system offers several advantages. Expert system knowledge bases will be used to construct the decision hierarchy with neural network modules acting as classifiers at the nodes of the tree. Neural networks such as Fuzzy ARTMAP can ...

Aiming at present as well as upcoming markets for coherent light sources with electrically controllable wavelength, CoreTek Inc. proposes a novel integrated-optic approach for widely tunable laser arrays. By integrating well established electrooptic materials and solid-state laser technologies, our proposed approach offers laser emission with finer than 1A linewidth and wide tunability range (170 ...

CoreTek Inc. proposes a novel photorefractive device that combines appropriate properties of new multiple quantum well and low temperature grown GaAlAs technologies to surpass by an order of magnitude previous material performance shortfalls. Our proposed devices will have nearly ideal characteristics for optical correlation and other 2D image processing applications: diffraction efficiency >6%, r ...

CoreTek, Inc. proposes a novel integrated tunable diode laser for Military and Commercial applications. In our proposed approach broad tuning (50-1OOnm) is achieved via on-chip integration of a novel electro-optic thin film waveguide with semiconductor laser diodes. The high electro-optical properties of the proposed thin films allows simultaneous broad tuning and extremely narrow linewidth (5Onm) ...

CoreTek Inc proposes a rewritable ferroelectric thin film disk drive (Ferro-Disk), which is addressed optically and read out electronically. The Ferro-Disk stores data in the form of electric remnant polarization in a ferroelectric film. Because ferroelectric materials are radiation hardened, the Ferro-Disk is specially suitable for reliable data storage during space missions. The architecture a F ...
