Three-dimensional co-axial linear photonic switch

A method for forming a high-voltage photoconductive switch module, comprising:

• selecting a height value for a coaxial structure;
• forming, based on the height value, the coaxial structure that includes:
• a cylindrically symmetric outer conductor, and
• a cylindrically symmetric inner conductor;
• determining a thickness of a photoconductive material based on an inner radius of the outer conductor and an outer radius of the inner conductor;
• and
• forming the photoconductive material into a coaxial shape having the determined thickness and the height value, wherein the height value allows the photoconductive material to absorb light at a predetermined absorption efficiency at a predetermined wavelength, and
• forming the coaxial structure includes placing the coaxial photoconductive material between the cylindrically symmetric inner conductor and the cylindrically symmetric outer conductor, wherein the coaxial photoconductive material is configured to absorb light of the predetermined wavelength at the predetermined absorption efficiency and become electronically conductive between the inner conductor and the outer conductor at a breakdown voltage that is determined based on the thickness of the coaxial photoconductive material and separately from the predetermined absorption efficiency, and wherein the cylindrically symmetric inner conductor, the cylindrically symmetric outer conductor, and the coaxial photoconductive material are configured as a photoconductive switch.
