Under the auspices of the Dean of the Faculty of Assyria, the University, Associate Professor Dr. Kazem Aboud Al-Majidi, the Department of Biomedical Engineering organized a workshop on Sunday, corresponding to 1/29/2023 under the title (Digital Simulation of Optical Devices), prepared and presented by M. Dr. Shahd Imad Younes, Lecturer in the Department of Medical Engineering Al-Hayati and the supervision of Prof. Dr. Ali Hussein Etewi, Head of the Department. The workshop, which was attended by a number of teachers and students, dealt with the subject of light waves and their applications in daily life. Photonics studies the properties of light, its generation, its transmission, and the conversion of light signals into electrical signals and vice versa, in addition to modern applications of science Photonics in communication systems and medical applications. It also has an important role in shortening the time and cost of devices in the quantitative pre-manufacturing process.
