Abstract:
1. A method for mitigating ionic migration in a waveguide, the method comprising: selecting a Titanium-diffused waveguide material for forming a first section of a waveguide to propagate light within an interferometer based on a criteria of making the first section of the waveguide not susceptible to ionic migration under non-atmospheric conditions; selecting a proton-exchanged waveguide material to propagate light within the interferometer for a second section of the waveguide that does not include the first section of the waveguide; and producing an integrated optical circuit for the interferometer comprising the first section of the waveguide and the second section of the waveguide, wherein stitching the first section of the waveguide to the second section of the waveguide further comprises aligning a crystalline structure of the first section of the waveguide with a crystalline structure of the second section of the waveguide so that the interferometer possesses an extinction ratio equivalent to the extinction ratio of the second section of the waveguide.
