THIS PROPOSAL ADDRESSES THE DEVELOPMENT OF A SOLID STATE LASER SCANNER FOR ROUTING A HIGH ENERGY LASER BEAM AMONG THE FIBER OPTIC ENERGY TRANSFER PATHS OF A LASER ORDNANCE INITIATION SYSTEM. A SOLID STATE LASER SCANNER WITH NO MOVING PARTS WILL ENABLE A MORE COMPACT AND DURABLE LASER ORDNANCE INITIATION SYSTEM. APA OPTICS' SOLID STATE LASER SCANNER UTILIZES INTERGRATED OPTIC WAVEGUIDES OF ALGAAS A ...

HIGH SPEED OPTICAL LINKS ARE FINDING EVER INCREASING USES INOPTICAL COMMUNICATIONS AND SIGNAL PROCESSING APPLICATIONS. CURRENTLY AVAILABLE PLANAR WAVEGUIDE LASERS USED IN THESE LINKS SUFFER FROM A HIGH INSERTION LOSS DUE TO A MODE MISMATCH BETWEEN THE FIBER AND THE MODULATOR AND THE INABILITY TO IMPLEMENT A 2D ARRAY CONFIGURATIONS. THE VERTICAL CAVITY SURFACE EMITTING LASERS (VCSEL) CURRENTLY UNDE ...

THE PROPOSED PROGRAM IS AIMED AT DEVELOPING ALX GA1-XN/GAN HETEROSTRUCTURE DEVICES FOR HIGH TEMPERATURE SENSOR AND ELECTRONICS APPLICATIONS. WE WILL FOCUSS ON AN ALXGA1-XN BASED HIGH ELECTRON MOBILITY TRANSISTOR (OR HEMT) FOR USE ASA HIGH TEMPERATURE MICROWAVE DEVICE OR AS A SENSITIVE ULTRAVIOLET DETECTOR. GAN HAS A LARGE BANDGAP OF 3.2 EV WHICH GIVES IT A GREATER BREAKDOWN VOLTAGE AND A HIGHER SA ...

WE PROPOSE A PHASE I RESEARCH PROGRAM AIMED AT DEPOSITING SINGLE CRYSTAL BN FILMS OVER SAPPHIRE AND SILICON CARBIDE SUBSTRATES. OUR PLAN IS TO EMPLOY A UNIQUE PHOTO-ASSISTED SWITCHED ATOMIC LAYER EPITAXY PROCESS. THIS WE FEEL WILL REDUCE THE SINGLE CRYSTAL EPITAXY TEMPERATURE VALUES CLOSE TO 1400C. WE ALSO PROPOSE TO USE A UNIQUE MULTILAYER BUFFERING PROCEDURE TO DECREASE THE INTERFACE DEFECTS RES ...

THE SELECTION OF A POLYMER FOR USE IN A BIOMEDICAL APPLICATION IS BASED UPON THE PHYSICAL CHARACTERISTICS OF THE POLYMER SUCH AS STRENGTH AND FLEXIBILITY AND UPON THE BIOCOMPATIBILITY OF THE MATERIAL WITH TISSUE. IT IS FREQUENTLY THE CASE THAT COMPROMISES MUST BE MADE BETWEEN THESE TWO POTENTIALLY CONFLICTING REQUIREMENTS. THE IDEAL SOLUTION TO THIS PROBLEM IS TO ENABLE THE SELECTION OF THE POLYME ...

THE CURRENT COMPUTER MODELS FOR REACTORS EMPLOYING CHEMICAL VAPOR DEPOSITION (CVD) ARE BASED ON SEVERAL SIMPLIFYING ASSUMPTIONS REGARDING THE PHYSICS OF THE FLOW AND CONFIGURATION. THESE MODELS CANNOT BE USED FOR ANALYZING 3DFLOWS IN COMPLEX CONFIGURATIONS. FURTHER, THESE MODELS ARE NOT COST EFFECTIVE. THE OBJECTIVE OF THE PROPOSED WORK (PHASE I AND II) IS TO DEVELOP AN EFFICIENT AND ACCURATE THRE ...

WE PROPOSE AN AUTOMATED MOLECULAR BEAM EPITAXY (MBE) PROCESS FOR REPRODUCTABLE GROWTH OF SEMICONDUCTOR DEVICE STRUCTURES. WE WILL APPLY RHEED AND THERMAL OSCILLATION TECHNIQUES TO CONTROL THE RATE ANDCOMPOSITION OF THE LAYERS AND TO ENSURE THAT THE GROWTH PROCEEDS UNDEROPTIMUM CONDITIONS. A MASS SPECTROMETER WILL BE USED TO CONTROL DOPANT INCORPORATION LEVELS. FLUXES FOR OPTIMUM GROWTH OF THE DIFF ...
