Luca Alloatti, Dinis Cheian, Rajeev Jagga Ram

摘要:

提出了一种利用T形横向pn结实现有效调制的微耗尽型调制器,同时最大化RC限制带宽。该器件具有13 GHz的3 dB带宽,已在标准的45 nm微电子CMOS工艺制造。该腔的线宽为17 GHz,在反向偏压条件下的平均波长偏移为9 pm/V。

英文摘要:

A microring depletion modulator is demonstrated with T-shaped lateral p-n junctions used to realize efficient modulation while maximizing the RC limited bandwidth. The device having a 3 dB bandwidth of 13 GHz has been fabricated in a standard 45 nm microelectronics CMOS process. The cavity has a linewidth of 17 GHz and an average wavelength-shift of 9 pm/V in reverse-bias conditions.
