HYBRID INTEGRATION OF PHOTONIC CHIPS WITH SINGLE-SIDED COUPLING

摘要

According to an example aspect of the present invention, there is provided a method for integrating photonic circuits (201, 203) comprising optical waveguides (204, 205), where a smaller chip (203) with at least one first photonic circuit is aligned and bonded on top of a larger chip (201) having at least one second photonic circuit in order to couple light between optical waveguides (204, 205) on each chip (201, 203), wherein optical coupling between the waveguides (204, 205) on said chips (201, 203) occurs from a single side (211) of said smaller chip.
