Two novel electro-optic deflectors using parabolic and half-horn designs offer excellent deflection angles and potential for optical switches. Fabricated devices show promising low insertion loss and high deflection performance.

Area of Science:

  • Photonics and Optical Engineering
  • Materials Science

Background:

  • Electro-optic (EO) deflectors are crucial components in optical switching and routing.
  • Existing EO deflector designs face limitations in deflection angle and potential for nonblocking switch architectures.

Purpose of the Study:

  • To introduce two novel nonrectangular geometries for electro-optic deflectors: parabolic and half-horn configurations.
  • To evaluate the performance of these new EO deflectors and compare them with existing technologies.
  • To explore their potential for constructing nonblocking 2x2 optical switches.

Main Methods:

  • Design and fabrication of novel electro-optic deflectors utilizing parabolic and half-horn geometries.
  • Experimental characterization of deflection angles and insertion loss.
