Description

It was found recently that large area Bi2Sr2CaCu2O8+δ (Bi2212) mesas show terahertz emission due to intrinsic Josephson junctions (IJJ). We have fabricated large and tall Bi2212 mesas by optical and electron beam lithography, and studied effects of fabrication technique on THz emission characteristics. Monitoring the emission was performed with a Si composite bolometer, while the applied current through the IJJ stacks was slowly swept by a function generator. Emission peaks were observed on I-V return branches while the bias current was decreasing. The frequency of emission was determined by a terahertz interferometer. The observed emission frequencies match the frequency calculated by the cavity resonance condition.
