New type phase-only wavelength division multiplexer
Zhongguo Jiguang/Chinese Journal of Lasers(1997)
Abstract
Using Y-G algorithm, substituting the discrete components such as gratings, and lenses by two binary phase-only elements H1 and H2, the new type phase-only wavelength division multiplexer (WDM) is designed. The phase modulation of H1 makes the intensity distribution on the output plane H2 satisfy the design that eight Gaussian beams are arrayed according to their wavelengths and their crosstalk is little. H2 transforms the wavefront of the output laser beam to couple well to each receiving channel. By only phase modulation, the demultiplexing, focusing, etc., of the WDM are realized.
