This paper describes the performance of planar back-to-back Barrier-N-N+ (bbBNN) devices for mm and submm wave multiplier applications. A technique has been developed for characterizing planar bbBNN devices with Vector Network Analyzer, which gives both the series resistance and voltage dependent capacitance of the device.

An all-solid-state, high-resolution and frequency-calibrated THz spectrometer based on optical heterodyne in low-temperature-grown (LTG) GaAs been constructed.
Alternative approaches for developing 2.0- 2.5 um single frequency semicondoctor lasers are reviewed.
High-resolution laboratory spectroscopy is utilized as a diagnostic tool to determine noise and harmonic content of balanced [9]-[11] and unbalanced [12]-[14] multiplier designs. Balanced multiplier designs suppress unintended harmonics more than -20dB. Much smaller values were measured on unbalanced multipliers.
