Early in the research, Jang snapped this photo of a diffraction pattern created by a metasurface. Says Jang: "The varying intensities of individual diffraction spots actually follows the predicted values that were calculated from the original 'design' of the randomness. That was a critical moment for us because that result implies that the optical randomness now can be 'controlled,' which contradicts with the traditional concept of optical randomness."

The latest advance in a new type of optics aimed at improving microscopy started with a game of tennis three years ago between Mooseok Jang a graduate of Professor Changhuei Yang's lab and Yu Horie working with Professor Andrei Faraon. "The hope is that our work will prompt further interest in this area of optics and make this type of microscopy and its advantages feasible for practical, everyday use—not just as a proof of concept," says Josh Brake, a graduate student in Yang's lab who continues to work on the project with Faraon and Yang.

Dr. Haowen Ruan and Mooseok Jang
Student Research in Biomedical Optics Wins First Place

Electrical Engineering postdoctoral scholar Dr. Haowen Ruan and graduate student Mooseok Jang, who work with Professor Changhuei Yang, have won first place for Best Student Poster Presentation at the Engineering Conferences International (ECI) series entitled “Advances in Optics in Biotechnology, Medicine and Surgery XIV.” Their winning poster demonstrated research in biomedical optics, specifically a novel technique that focuses light inside biological tissue by time-reversing the light encoded through popping of a microbubble. The technique has the potential to enable one to “see” through biological bodies with light.
