Interests: Micro Cavities, Lasers, Optics, Photonics. Semiconductor nanostructures, Electronic Circuits.I was born and raised in Lima, Perú and now living in the USA since 1999. I worked as Manufacturing and Service Engineer for the semiconductor industry for about 9 years, before returning to school. I built, tested, and maintained metrology characterization equipment for measuring transparent films stacks (ellipsometers) and opaque film stacks in a non-contact manner. It uses an ultra-fast laser to generate sound waves that pass down through a stack of opaque films and send back to the surface an echo signal that indicates film thickness, density and other film properties.

My doctoral dissertation was conducted under the direction of Dr. Daniel Stick and Dr. Peter Maunz at Sandia National Laboratories and looked at the implementation of a cavity integrated with a surface linear ion trap for light enhancement. The goal was to collect ion-emitted photons efficiently for enabling faster remote entanglement generation. In my research I designed, analyzed, and integrated the optical system for the cavity into the surface trap as well as the cavity matching system for the lasers coupled into the cavity. The integration of this system required the design and construction of a UHV chamber, a cavity that fit into the surface ion trap chip, and experience with ion trapping techniques.

During my graduate training I had the opportunity to work in other projects aside from my dissertation work. I designed and built external cavity diode lasers as well as tapered amplifiers. I built and locked a laser system with narrow linewidth that was stabilized to a high finesse cavity made of ultralow expansion material. I was a member of the experimental team assisting in the ion trapping side and ring cavity alignment for the frequency translation of a single calcium ion project. Additionally, I designed, layout, diagnosed and populated diverse electronics circuits.
