We will have 4 10 min presentations;

Until recently, non-circular core geometries(e.g., square or rectangular)of multimode fibers (MMFs) have not been investigated with wavefront shaping. In this research project, I perform wavefront shaping through MMFs using Lee Holography and concludethat both square and rectangular core MMFs present attractive frequency bandwidths when focusing light at the distal end of the MMF, enabling new experimental opportunities in photonics.

2D materials have great potential in electronic device applications such as FETs as well as in optoelectronic devices like semiconductor waveguides. In this short presentation we would learn about some of the methods commonly used to prepare 2D materials and heterostructures as well as investigate their properties in the visible and near-infrared spectrum.

Due to the limitations and expenses imposed by commercially available infrared equipment, research into the temperature and thickness dependent properties of 2 dimensional materials necessitates the production of a custom built cryogenic infrared microscope. This custom microscope needs to be developed using widely available parts, broadband for multiple possible use cases, and simple enough to be assembled without expertise due to the lack of documentation in this area

In order to innovate an analyze current detection methods of Volatile Organic Compounds, we have developed our own fitting program and system to detect compounds. Using gas spectroscopy, we will be able to improve detection with the end goal being in the PPB
