A doctoral student in electronics and computer engineering, working in Professor Jay Guo's laboratory on ultra-thin thin films based OLED (Figure: Robert Coulius/Michigan engineer). The research team used an ultra-thin film as a transparent electrode and conducted a systematic modal analysis of OLED. It was pointed out that by designing an OLED structure with a thickness lower than the waveguide mode cutoff, the waveguide mode can be completely eliminated. Experimental verification of waveguide modes in organic optical waveguides was conducted using refractive index matching solution and prisms. The negative dielectric constant
