Description:

The EECS Department & CQD Center welcome Dr. Lin Zhu, Associate Professor of ECE Dept. at Clemson University.

Zhu will present a talk entitled "Monolithic & Hybrid Photonic Integration for Beam Combining of Diode Lasers", on Monday, March 20 at 11:00 AM in the Cook Hall Room 2058.

Abstract: In this talk, we will first discuss monolithic coherent beam combining of angled-grating broad-area lasers. We have obtained simultaneous coherent beam combining and single transverse mode operation for broad area lasers on a single chip through the integrated diffraction coupling and transverse Bragg resonance. Our approach has also been extended to a zigzag laser super-cavity for array size and power scaling. In addition, we have demonstrated the single frequency operation and coherent beam combining of broad area lasers by using photonic crystal DFB structures. We will then discuss hybrid integration of the chip-scale laser beam combining systems in silicon photonics platform.

Bio: Dr. Lin Zhu is currently the Associate Professor of Electrical and Computer Engineering Department at Clemson University and is also the program coordinator of Photonics Graduate Program. He obtained the Ph.D. in Electrical Engineering from California Institute of Technology in 2008. Dr. Zhu’s current research interests include laser beam combining, hybrid photonic integration, optomechanics, and nanophotonic devices. He has published more than seventy peer-reviewed journal and conference papers. His work has been funded by many federal agencies, including ARO, DARPA, HEL-JTO, NSF, and USARMY SMDC. Dr. Lin Zhu was the recipient of the DARPA Young Faculty Award, ARO Young Investigator Award, and ORAU Ralph E. Powe Junior Faculty Enhancement Award. He has served on the technical committees of many IEEE and OSA photonics conferences.
