A novel fiber-based Terahertz source

摘要

One kind of novel fiber-based Terahertz source — opt-THz fiber is proposed, it is based on the second order nonlinearity in the poled optical fiber, where optical fiber is used to transmit optical pump power and distributely generate Terahertz fields while outside Terahertz fiber is used to transmit Terahertz wave. Simulations have been done and optimized designs are given.
