Design Fiber Optic Communication Products

using Free Space Optics and Guided Wave Optics

(1)

 

Abstract The boom of fiber optic communication networks has facilitated the advancement of optical component and system design utilizing both free space optical systems as well as the guided optical system. Depending on the function the fiber optical system plays in communication networks, the number of signal channels, manufacturing difficulties, CapEx and Opex, either the free space optical system or the guided wave optical system will be selected. In the first part of this seminar, presented on March 14, I will display exemplary design cases used in communication networks using the free space optical system. During the second part of this seminar, the exact date to be announced later, I will present fiber optical communication devices and module designs using guided optical systems. A set of exemplary products manufactured using planar lightwave circuits will be discussed.

Biography Dr. Chun He is currently the Director of Engineering at Gemfire Corporation. He has formerly served roles as Engineering Managers, Chief Product Designers, and Chief Engineers in several fiber optical component and module companies. He has twenty years successful research and product development experience in semiconductor lasers, surface science, and photonics. He pioneered virtual optical experiment and virtual manufacturing methodology in free space fiber optical system design using computer modeling. This approach has not only ultimately optimized product designs, but also significantly reduced product development cycle time and product cost. His recent work has been focused on hybrid bonding of planar lightwave circuit modules manufactured on different materials and substrates, integration of micro optics with planar lightwave circuit, and low cost packaging in photonic products. Chun He received his Ph.D. degree from Pennsylvania State University in 1990, majoring in Physical Chemistry. He has published over 80 peer-reviewed articles in professional journals, including Nature, Physical Review Letters, Physical Review, Applied Physics Letter, and Journal of Chemical Physics, and over 30 invited talks in international and national symposiums and workshops. He has 11 granted US patents, 1 granted China patent, and 6 pending US patents in device fabrication, fiber-optics, and semiconductor lasers.
