High-Power Terahertz Generation from Optically-Pumped Graded Composition InGaAs Structures

Not Accessible

Your library or personal account may give you access

Abstract

We present a record-high-power photoconductive terahertz emitter operating at 1550 nm wavelength, which utilizes graded composition InGaAs structures integrated with plasmonic nanoantennas. We demonstrate 860 µW pulsed terahertz generation at 900 mW optical pump power.
