| Abstract(in English) | Optical coupling between stacked waveguides by grating couplers integrated on each guiding layer was proposed for use in multi-story waveguide devices. The coupling characteristics, such as power transfer, coupling efficiency, wavelength selectivity, were analyzed based on the coupled-mode theory. It was found that in forward coupling there is very small wavelength selectivity and the coupling efficiency cann't be very high. In backword coupling, on the other hand, a very sharp wavelength selectivity and a very high coupling effiency can be obtained. A backward coupling device was designed, fabricated and characterized for 0.8μm coupling wavelength using TE modes. A 0.3nm wavelength bandwith of coupling effiency, close to the calculated result of 0.2nm, was obtained and a very sharp wavelength-selective coupling was demonstrated experimentally. |
