  • Abstract
    We demonstrate a long-wavelength detector structure using an undercut mesa and an air-bridged coplanar metal waveguide to significantly reduce both the diode RC constant and the parasitic capacitance. Record electrical bandwidths of 120 GHz are demonstrated for long-wavelength photodetectors.
