1. A method for producing light-guiding structure comprising:

  • providing a substrate having a top substrate surface;

    forming in the substrate a first cladding layer having a first porosity value, said first cladding layer having a body portion disposed below said top substrate surface and one or more end portions terminating in said top substrate surface;

    forming in the substrate a waveguide core layer in contact with the first cladding layer and having a second porosity value less than the first porosity value, said waveguide layer having a body portion disposed below said top substrate surface and one or more portions terminating in said top substrate surface; and

    forming in the substrate a second cladding layer in contact with the waveguide core layer and having a third porosity value greater than the second porosity value, said second cladding layer having a portion terminating in said top substrate surface.
