OPTICAL WAVEGUIDE INTERFEROMETER COMPRISING A LAMINATE STRUCTURE WITH A FIRST PLANAR WAVEGUIDE MONOLAYER AND A SECOND SANDWICH LAYER
摘要
<p>The present invention relates to an optical waveguide interferometer comprising a laminate structure with a monolayer constituting a first planar waveguide (2) and a sandwich layer constituting a second planar waveguide (4), wherein the laminate structure is integrated with a lowermost substrate (5) and comprises the second planar waveguide (4) located above and spaced apart from the first planar waveguide (2) by a spacer monolayer (3). The sandwich layer (4) comprises a first layer (4a) exhibiting a first refractive index spaced apart from a second layer (4c) exhibiting a second refractive index by a spacer (4b), wherein the refractive index of the spacer (4b) is less than that of the first refractive index and of the second refractive index.</p>
