Abstract
The present invention relates generally to electro-optically active waveguide segments, and more particularly to the use of a selective voltage input to control the phase, frequency and/or amplitude of a propagating wave in the waveguide. Particular device structures and methods of manufacturing are described herein.
Claims67
A method for manufacturing an electro-optic waveguide segment having a core and a cladding;
- the method comprising the steps of:
- removing a first selective portion of said cladding to form a first recess within said cladding, the first recessed cladding region having an outer dimension which is less than an unmodified section of said cladding;
- depositing a first electrically conductive material within said first recess, thereby forming a first electrode;
- placing said waveguide segment on a second electrically conductive material;
- said first and second electrically conductive materials not being in direct contact;
- and
- poling said fiber segment using at least a electric field applied to said first electrode to induce a non-linearity in said waveguide segment.

A method for manufacturing an electro-optic waveguide segment having a core and a cladding;
- the method comprising the steps of:
- removing a first selective portion of said cladding to form a first recess within said cladding, the first recessed cladding region having an outer dimmension which is less than an unmodified section of said cladding;
- depositing a first electrically conductive material within said first recess, thereby forming a first electrode;
- removing a second selective portion of said cladding to form a second recess within said cladding, the second recessed cladding region having an outer dimmension which is less than an unmodified section of said cladding, said first and second recesses not contacting oneanother;
- depositing a second electrically conductive material within said second recess, thereby forming a second electrode;
- and
- poling said fiber segment using at least a electric field applied to either said first or second electrode to induce an non-linearity in said waveguide segment.
