Abstract

Abstract : In article number 2100057, John E. Bowers, Yating Wan, Chao Xiang, and co‐workers report record‐setting quantum dot (QD) distributed feedback lasers on Si with a 3‐dB modulation bandwidth of 13 GHz, a threshold current of 4 mA, a side‐mode‐suppression‐ratio of 60 dB, and a fundamental linewidth of 26 kHz. The broadband QD lasers and the Si‐on‐insulator waveguiding platform can be expanded to build fully functional photonic integrated circuits throughout the O band.
