Abstract:
A graphical user interface and method for customer centric network management. The graphical user interface includes a first view showing text input by a user indicative of customer identification data corresponding to a customer in a network. This data is received by a server connected to the user. The server retrieves stored information corresponding to the customer identification data from a database and provides the stored information and actual circuit path information corresponding to a customer service based on the stored information to the graphical user interface. A second view of the graphical user interface shows the stored information, and a third view shows a graphical representation of a customer path corresponding to the actual circuit path information.
Abstract:
A ridge-waveguide laser is fabricated by epitaxially growing a GaAs-based heterostructure, disposing an AlAs etch stop layer on the heterostructure, disposing epitaxial layers on the etch stop layer, and etching the heterostructure to form the laser whereby the etch stop layer prevents further etching into said heterostructure.
Abstract:
An IMSM photodetector structure comprises a GaAs substrate, a buffer region grown on the substrate, an optically active absorbing layer of In.sub.0.42 Ga.sub.0.58 As grown on the absorbing layer. The buffer region includes in sequence a first layer of In.sub.0.23 Ga.sub.0.77 As, an In.sub.0.46 Ga.sub.0.54 As/GaAs superlattice, and a second layer of In.sub.0.23 Ga.sub.0.77 As. An interdigitated pattern of Schottky metal contacts is fabricated on the Al.sub.0.3 Ga.sub.0.7 As/GaAs superlattice. This structure is useful in fabricating long-wavelength, monolithic receivers based on GaAs MESFET technology since the optical and electrical characteristics of the structure are preserved during the thermal annealing cycle necesary in ion-implaned GaAs MESFET processes.

Abstract:
A method of fabricating a semiconductor heterostructure includes the growth of a quantum well active region that is highly lattice-mismatched relative to a substrate. A buffer layer having a thickness above a critical value is grown on the substrate whereby the stress due to a lattice constant mismatch between the buffer layer and substrate is relieved through the formation of misfit dislocations. A strained superlattice structure is grown on the buffer layer in order to terminate any upwardly-propagating dislocations. An unstrained barrier layer is subsequently grown on the superlattice structure. The fabrication method concludes with the growth of a quantum well structure on the unstrained layer wherein a lattice constant mismatch between the quantum well structure and the unstrained barrier layer is smaller than the lattice constant mismatch between the quantum well structure and the substrate. As a result, only a fraction of the stress due to the large lattice mismatch between the quantum well structure and the substrate is accommodated by coherent strain in the quantum well structure, while the remainder of the stress is relieved through the formation of misfit dislocations spatially separated from the quantum well structure.
Abstract:
A method of selectively tuning the bandedge of a semi-conductor heterostructure includes forming a disordered region which is spatially separated from a quantum well active region, and subsequently annealing the heterostructure so that vacancies/defects in the disordered region diffuse into the quantum well region and enhance interdiffusion at the well-barrier heterojunctions. The tuning is spatially selective when the heterostructure is masked so that exposed portions correspond to regions where bandgap tuning is desirable. The heterostructures of interest are III-V material systems, such as AlGaAs/GaAs, where the active region includes structures such as a single quantum well, a multiple quantum well, or a superlattice.
Abstract:
An array of bistable devices includes a thin cadmium sulfide platelet having a first portion thereof that is substantially pure and the remaining portion thereof is implanted with atoms that can bind excitons. Such remaining portion can be implanted with ions from a lithium source. Apparatus for providing such an array can include a source of lithium ions and masking means for selectively permitting and for selectively inhibiting passage of ions from the source to pass therethrough and to implant in a pattern onto the platelet. The apparatus operates at temperatures in the neighborhood of liquid helium. A method for producing such an array includes providing a thin, substantially pure, platelet of cadmium sulfide, selectively masking the platelet with a pattern to selectively permit and to selectively inhibit passage of ions onto the platelet, and providing a source of ions. The source of ions, in accordance with certain features, can be lithium ions.
