Novel intelligent fiber-optic value-added modules (VAMs) utilize spatially multiplexed processing with micromirrors for reconfigurable optical power splitting. This technology offers precise control for optical systems, demonstrating high repeatability and various tap ratios.

Area of Science:

  • Photonics and Optical Engineering
  • Microelectromechanical Systems (MEMS)
  • Fiber Optics

Background:

  • Traditional fiber-optic systems often lack dynamic power-splitting capabilities.
  • Reconfigurable optical modules are crucial for advanced optical networks and signal processing.
  • Existing solutions may involve complex or bulky components.

Purpose of the Study:

  • To propose and demonstrate a novel, reconfigurable fiber-optic value-added module (VAM).
  • To implement a spatially multiplexed processing technique for precise optical power control.
  • To enable dynamic optical power split states for advanced optical applications.

Main Methods:

  • Utilizing a novel spatially multiplexed processing technique with reconfigurable and nonreconfigurable pixels.
