3-μm中红外偏振无关且CMOS兼容的石墨烯调制器
3-μm mid-infrared polarization-independent and CMOS-compatible graphene modulator
摘要
Abstract
This paper proposes a 3-μm mid-infrared band polarization-independent and CMOS-compatible gra?phene modulator,which mainly includes two parts:the mode conversion structure and the graphene modulator. This modulator not only fulfills the requirement of compatibility with CMOS,but also can achieve polarization-in?dependent modulation of the fundamental mode. Simulation results show that this modulator can achieve an ex?tinction ratio(ER)higher than 20 dB in the mid-infrared band from 2. 95μm to 3. 05μm,the insert loss for both TE and TM modes are less than 1. 3 dB,and polarization-dependent loss is less than 1. 09 dB. Through the calcu?lation,the 3 dB bandwidth up to 9. 47 GHz can be obtained when the length of the device is 420μm.关键词
