Summary:Hardware, firmware and software development for consumer electronics devices with a specialty in iPhone, iPad and iPod touch area. GPS engine and antenna design, USB interface design, microcontroller selection and firmware design. Verification testing, manufacturing and production management. Website and e-commerce development. Small business consulting and advice services.Details:I founded Emprum late 2009 after Apple officially allowed external accessories for its iPod touch, iPhone and iPad devices. I developed and brought into full production Emprum’s UltiMate GPS, designed to add GPS capability to Apple’s iPod touch, iPhone and iPad platforms. The completed product and manufacturing process was designed in house, from hardware, microcontroller selection and firmware design to software development, design verification, production, assembly procedure and production testing. Emprum’s UltiMate GPS accessory is fully licensed through Apple’s “Made for iPod” program and currently on the market for sale. It stands out among its competitors in various aspects of design, product quality, features and functionality, and user friendliness and ease of use. Other acquired business experiences include project/product management, management of partners, contractors, suppliers, manufacturers and inventory, online sales channel setup and infrastructure, product fulfillment, website development and accounting.

Summary:Hardware and software development for mobile devices with a specialty in iPhone, iPad and iPod touch area. GPS engine and antenna design. Verification testing and manufacturing and production management. Website and e-commerce development. Small business consulting advice and services.Details:I founded Orange Gadgets in the early days of Apple’s iPhone at a time when no external accessories were allowed by Apple. I developed and brought into full production the iGPS360 accessory designed to add GPS capability to Apple’s first generation iPhones. I took the product through a full development cycle: from initial prototyping stage and component selection, to hardware and PCB design, 3D CAD housing design, to full on-shore production, assembly and testing. Software was initially outsourced, but later refined in-house. The company became profitable after 3 months of sales. Other acquired business experiences include project/product management, management of contractors, suppliers, manufacturers and inventory, online sales channel setup and infrastructure, product fulfillment, website development and accounting.

Summary:Modeling, design, fabrication and testing of novel nano-photonic structures, semiconductor lasers and gain chips, external cavity lasers, and other optoelectronic devices. Extensive experience with photonic modeling software, electronic layout packages, statistical data analysis.Details:I designed, taped-out and tested various SOI based nano-photonic devices, including optical MZI and ring modulators, 1D/2D photonic crystal devices, external cavity laser feedback structures, thermal phase modulators and variable optical attenuators. I was part of various component development and improvement task forces, including high-speed modulator and laser development efforts. I initiated and proved the feasibility of the first 10Gbits/sec Si ring modulator which was subsequently successfully prototyped. I have tested, characterized and modeled high-speed silicon devices and various III-V lasers and gain chips for development purposes and application in external cavity lasers. I have researched Raman based Si lasers and highly doped Si PiN-junctions for light emission. I am familiar with and have extensively used the concepts of DOEs/DORs for new device development and improvement, as well as the concept of statistical data analysis and software for device measurements. I have extensive hands-on lab and prototyping experience. In the CAD design area, I was overall layout integrator for multiple SOI tape-outs, and have implemented and managed a wafer-scale test-scheduling database. I identified, evaluated and recommended software solutions for optical device simulation and have developed various in-house software, among which a photonics development kit for layout integration of Cadence with Matlab, and software for an intuitive visual k-space representation of the EM-field emitted by photonic devices. I have developed software in Visual Basic for test and measurement purposes. I worked on various optical modulator related patents.

Summary:Modeling, design, fabrication and testing of novel fiber lasers, fiber Bragg gratings and other optical components. Active and passive temperature compensation of optical components using negative expansion material and bi-metal packages. Low expansion adhesives, UV and IR adhesive curing procedures and equipment. Optical mixing, RIN, RF and noise measurements. High strength fiber stripping, cleaving, splicing and recoating. Splice optimization for dissimilar fibers.Details:I modeled, designed, developed and manufactured a new type of fiber laser in a virtual ring configuration with ultra-stable and low phase-noise operation. I designed and tested various fiber Bragg gratings and resonator designs for use in this laser. I modeled the thermal behavior of the laser and developed a packaging method to reduce the temperature drift in the optical laser oscillation frequency to less than +/-5GHz over 60 degrees. A full development-to-production cycle was completed and the resulting laser product was sampled to customers. I was the main contributor to the patent issued for this new type of fiber laser.
