Our project concentrates on using PlanOpSim’s optimization algorithm software to enhance the efficiency and functionality of nanostructured optical devices. Unlike traditional engineering methods, in which a structure is designed and then tested, inverse design begins with a target optical response and uses computational methods to determine the optimal nanostructure to achieve that function. For our first objective, we designed a metasurface capable of displaying two distinct holographic images depending on whether the incident light is in the TE or TM polarization state. For the second, we aimed to design a metasurface that produces specific colors by controlling the interaction of light with carefully engineered nanostructures.

The low numerical aperture multimode fiber project is a detailed fiber design and simulation developed by a team of undergraduate senior students. As such, the inputs were determined through discussion with our project customer, ASML. We are designing a fiber to support ASML’s YieldStar (YS) optics sensor for scanning wafers using white light with the wavelength range of 400 to 1000 nm and another fiber to operate at a wavelength of 1070 nm meant to preheat a mirror for a separate lithography machine.
