Optical device and method of making

An electro-optical device, comprising;

• a wide-bandgap semiconductor substrate having a first optical property;
• an optical device defined within the wide-bandgap semiconductor substrate having a second optical property different from first said optical property;
• said optical device defined by a plurality of optical surfaces with all of said plurality of surfaces being internal to said wide-bandgap semiconductor substrate;
• and
• a first and a second electrode located in proximity to said optical device for changing said second optical property upon a change of a voltage applied to said first and second electrodes.
