Abstract
We present two novel applications of optical properties of the interference wedge (compact realization of the Fizeau Interferometer) for the case of illumination with a small diameter laser beam. The first one is a new and competitive wavelength division multiplexing structure. The main advantages of the device are the possibility for separate frequency tuning of each input-output channel as well as its compactness. The made computer simulation proves that the structure can work with very short laser pulse duration (~ 0.1 ns), which corresponds to pulse repetition rate of order of ten GHz and more, thus fulfilling the requirements of modern digital communication systems. The theoretical analysis and the experimental check with laboratory model of a free-optical communication system show a sufficient resonant narrowline transmission up to 75% with the linewidth of emission from 0.05 nm to few nm. The second proposal is a device which allows for distant laser measurement of small linear translation of a rigid object for distances from a few meters up to hundred meters.
