Abstract

We experimentally demonstrate that the spectral resolution of Fourier transform interferometer could be greatly enhanced by utilizing the dispersive property of semiconductor GaAs in the near infrared region and it is inversely proportional to the maximum group delay time that can be achieved in the system. The spectral resolution could be increased 6 times approximately by using GaAs contrast with conventional FT interferometer under the same conditions.
