报告摘要:

硅基电光调制技术具有巨大的潜力,能够满足通信和计算领域迅速增长的带宽需求,是未来光电融合技术的核心之一。本次报告聚焦于作者在硅基电光调制器方向的研究进展及未来技术革新的思考,具体包含4个方面:

(1)微型全硅电容波导电光调制器及其与低压驱动器的集成;

(2)载流子电吸收增强的微环调制技术;

(3)大规模高带宽密度微环无纠错链路;

(4)硅基二次电光效调制器在空间和量子通信的潜力。

Integrated electro-optic modulators offer huge potential to meet communications and computations' rapidly growing bandwidth requirements. Devices based on silicon allow high-volume, low-cost CMOS fabrication, and co-integration with the CMOS circuits. They are promising candidates for mass-producible Tb/s-scale inter-rack and intra-rack interconnects. This talk will focus on our advancement of silicon-based optical modulators: (1) miniaturized all silicon MOSCAP modulators for co-packaged optics and its integration with low voltage drivers, allowing low optical power consumption of 2 pJ/bit. (2) Novel carrier absorption enhanced electro-optical modulation in MOSCAP ring resonators towards integration with ultra-low voltage (<1V) CMOS drivers; (3) Carrier depletion ring unity device for large scale and high bandwidth density error-free link
