Abstract :
We have succeeded in investigating the terahertz transmission property of fiber-coupled micro-strip-line, aiming at utilizing the functionalized transmission line as a remote sensor head. Using a single-mode optical fiber, the spectral width of 1.2 THz is obtained after the 1 mm propagation of THz pulses. The width is narrower than that of 1.7 THz determined without using the optical fiber. The degradation would be attributed to the broadened optical pulses after propagating through the optical fiber.
