Low Voltage Graphene-Based Amplitude Modulator for High Efficiency Terahertz Modulation

Low Voltage Graphene-Based Amplitude Modulator for High Efficiency Terahertz Modulation

In this paper, a high-efficiency terahertz amplitude modulation device based on a field-effect transistor has been proposed. The polarization insensitive modulator is designed to achieve a maximum experimental modulation depth of about 53% within 5 V of gate voltages using monolayer graphene. Moreov...
