(a) Time domain measurement and (b) Spectrogram of the THz emitter. (c) Time domain measurement of the E-field of the THz waves transmitted through the TOPAS SC-MPOF; the blue and red lines represent the signal from the whole fiber (core and outer cladding) and from the fiber core only, respectively. (d) Spectral profile of the THz waves transmitted through the TOPAS SC-MPOF. Spectrogram of the THz wave guided (e) in the whole fiber cross section (outer cladding and core); and (f) fiber core only of an 80 mm long SC-MPOF.
