A Coherent, Tunable, FIR Source

Authors:
J. H. Brownell, M. F. Kimmitt, J. C. Swartz, J. E. Walsh
Abstract:
A tunable coherent source which operates in the THz-FIR region of the spectrum has been developed. The device, termed a grating-coupled oscillator (GCO) uses the beam in a scanning electron microscope (SEM) and a diffraction grating placed in the e-beara's focal region to generate the radiation. Distributed feedback is provided. by the grating itself and the e-beam is focused and positioned using the microscope's internal control system. A summary of operating characteristics of the present device and a survey of the scaling relations which will determine the spectral coverage is presented. Comments on what will be required in order to develop a very compact device are also included.
