Abstract
A method of producing a PLC based optical component comprising: defining a waveguide; etching a notch thereby defining a facet of the waveguide; and cutting a trench in front of the notch, the cutting being accomplished subsequent to the etching, whereby at least a portion of the trench is displaced from the facet by the notch. The invention also provides for a PLC based optical component comprising: a substrate; a waveguide deposited above the substrate, the waveguide exhibiting a facet; a notch etched in front of the facet of the waveguide; and a trench cut in front of the notch.
Claims23
A method of producing a PLC based optical component comprising:
- defining a waveguide;
- etching a notch thereby defining a facet of said waveguide;
- and
- cutting a trench in front of said notch, said cutting being accomplished subsequent to said etching,
- whereby at least a portion of said trench is displaced from said facet by said notch.
A PLC based optical component comprising:
- a substrate;
- a waveguide deposited above said substrate;
- a notch etched to the depth of said waveguide, said notch defining a facet of said waveguide;
- and
- a trench cut in front of said notch, said trench being displaced from said defined waveguide facet by said notch.
