　　报告摘要：

　　The functionality of photonic integrated circuits (PICs) is rapidly increasing and is having a major impact on applications in timing, navigation and data communications. Photonics can reduce energy consumption in information processing and communications while simultaneously increasing the interconnect bandwidth density. With the use of photonic integration and fiber optics, and the elimination of electrical line charging dissipation, we can save integrated circuit power by transmitting data from 1 mm to 1 km with the same energy (20 fJ/bit) and simplicity as local electrical wires on chip. A focus of our research is on using quantum dot (QD) lasers and integration on silicon for lower threshold and higher efficiency sources, higher temperature operation, isolator free operation, and superior mode locking capability. A recent example includes a 4.1 Tbps, 60 wavelength, 32 Gbaud PAM-4 transmitter using a single mode locked quantum dot laser.
