  • Compact fiber pigtailed terahertz modules
    Patent number: 6816647
    Abstract: An industrially hardened terahertz electromagnetic transmitter and receiver module (29) is disclosed. The electromagnetic wave module has an optic (30) which relays an optical pulse from the delivery fiber (32) to the terahertz device. The relay optic (30) allows for a greatly reduced optical spot size as compared to the output of the optical fiber. Thus, the sensitivity of the overall system is enhanced by improving the efficiency of the terahertz device. The relay optic (30) allows the small spot of light to be aligned to the electromagnetic transmitter or receiver with sub-micron precision.

  • Dispersive precompensator for use in an electromagnetic radiation generation and detection system
    Patent number: 6320191
    Abstract: An electromagnetic radiation emitter which utilizes a precompensator, pulsed light signal, optical fiber cable, and a terahertz radiation generator. The present invention incorporates an optical precompensator to correct for the stretching of an optical signal as it travels through an optical fiber cable. The dispersion characteristics of the precompensator will be equal and opposite to the dispersion characteristics of the optical fiber cable, maintaining the fidelity of optical pulses as they travel through and exit the optical fiber cable striking a device that generates terahertz electromagnetic radiation.
