Continuous wave terahertz systems exploiting 1.5 microm telecom technologies.

A fiber-assembled CW THz System operating at 1.5 microm is presented. High speed telecom photodiodes integrated with planar THz antennas serve as THz emitters with power up to 10 microW.

All-fiber terahertz time-domain spectrometer operating at 1.5 microm telecom wavelengths.

The worldwide first all-fiber THz time-domain spectrometer for operation at 1.5 microm is presented. Applications up to 3 THz are demonstrated.
