Abstract :
The durability of photoconductive Terahertz emitters significantly depends on bias voltage and/or optical power. We analyze the optimum operation conditions of photomixers for long-term performance and link the accessible signal-to-noise ratio to the photomixer lifetime via an Arrhenius analysis.
