Abstract
In the paper, a new concept of the 1×2 waveguide beam splitter has been presented, on the basis of gradient multimode interference structures made by Ag+ - Na+ ion exchange in glass with an arbitrary power splitting ratio at the output. The beam splitter, working in Mach-Zehnder configuration, consists of two asymmetrical MMI sections operating as 3dB couplers joined by monomode waveguides of different width. The operating characteristics of the 1×2 beam splitters have been determined for different geometry configurations of waveguides joining the MMI section. Self-imaging phenomena in MMI make possible to use in one of interferometer arm the multimode waveguide.
