摘要：
Photoconductive antennas (PCA) (one of the most commonly used terahertz emitters) have limited performance (e.g. low output power) and as such, do not fully meet the increasing needs of applications. This work attempts to find a route to further improve the performance of PCA by studying the dependence of emission properties on various parameters. Using substrates of LT-GaAs and SI-GaAs, the responses of PCAs with different structures are studied and compared.
