"I applied to the Scholar’s program to provide an incentive for my studies. Merely reading the literature is not enough. It’s easier to absorb a subject if you can actually see the material put into practical use. With that in mind, I also want to glimpse into the process of engineering. An important aspect of engineering is preparing feasibility studies, like mine. Regardless of whether I work in industry or academia, I will have to know how to integrate information and produce comprehensive reports."

An Investigation into the use of Metamaterials for Photonic Analog-to-Digital Conversion
The signal-processing community is always in need of ways to achieve ever-higher speed/bandwidth and bit resolution in Analog-to-Digital Converter (ADC) systems. ADC systems currently boast 12 bits of resolution at speeds up to 3.6 GSPS. Modern broadband communication and radar systems often require high resolution digitization capability with system bandwidths on the order of tens of Gigahertz, and systems have been developed that utilize a combination of analog RF/microwave technology along with systems of slower-speed ADCs to achieve those desired, yet still elusive system specifications. For decades, researchers have been intrigued by the tremendous bandwidth of laser/lightwave systems (photonics) as a means of implementing an all-photonic ADC. Though much success has been realized, limitations in the performance of photonic components often impede the resulting ADC performance. One goal of this investigation is to explore means of using photonic metamaterials to overcome some of the performance limitations encountered in the all-photonic ADC. The photonic metamaterials to be studied are Photonic Crystals (PC). These can be constructed so as to make the refractive index appear negative at a particular wavelength band, which allows for many new and interesting applications. For an ADC system, for example, a PC could refract light with incredibly high angular dispersion. This would allow for the spatial discrimination of the temporal line spectrum of a femptosecond laser allowing for efficient wavelength excision. These spatially dispersed beams of light could then be used as the basis for wavelength-based encoding of the signal to be digitized . The goal of this feasibility study is to establish the current limits and future trends of PC technology and to determine whether their use presents a practical solution to the problems posed by photonic analog-to-digital conversion.
