Abstract : Photoconductive Antenna (PCA) have been utilized extensively for the detection and generation for both pulsed broadband and single frequency continuous wave terahertz (THz) band radiation. THz frequencies range between 0.1 to 10 THz. This range is lying between optical and microwave area. Thesis devices results the form the various basis of THz spectroscopy and imaging systems that illustrated promising applications over various industries such as Medical, Product manufacturing and Aerospace. Solid and optical state approach are employed for the generation of THz radiation. However, the solid state design is constrained because the generation of THz radiation need to be done at cryogenic temperature. However, the optical generation is categorized as optical rectification and photoconductive generation. The Photoconductive generation is more efficient than the optical rectification when the standard laser oscillators are utilized. In PCA, the efficient and THz power generated are impacted through two critical parameters such as material properties and electrode geometry. Therefore, the present study employed four PCAs design for the generation and detection of THz. Further, the study considered, micro-fabrication concerns and aspects which are rarely deliberated in the existing studies. Hence, the study results the effect of different parameters such as adding adhesion layer in between substrate and electrodes, varying dipole length and gap properties and along with this the study also deliberated and compared the output frequency, photocurrent and total effective energy of different PCA models at different laser power values.
