Area of Science:

  • Optical Engineering
  • Photonics
  • Telecommunications

Background:

  • M x N port wavelength-selective switches (WSS) are vital for optical communication networks, enabling signal routing and management.
  • The port array module, responsible for fiber-to-spatial beam coupling, critically influences WSS performance parameters like port count and insertion loss.

Purpose of the Study:

  • To design and optimize a silicon micro-lens array for high-precision coupling in M x N port WSS.
  • To demonstrate a method for significantly increasing the port count of WSS devices.

Main Methods:

  • Utilized VirtualLab Fusion 2023.1 software for physical optics simulation and design.
  • Designed a silicon micro-lens array for precise coupling of a fiber array with 1143 μm pitch.
  • Manufactured the designed micro-lens and experimentally verified its beam focusing capabilities.

Main Results:

  • Achieved high-precision coupling of the fiber array with the designed micro-lens.
  • Demonstrated a 3 dB insertion loss in the manufactured micro-lens.
  • The micro-lens array system produced 28 focused spots (approx. 1mm 1/e2 diameter) over 300 mm, enabling a 28x28 port WSS.

Conclusions:

  • The developed silicon micro-lens array design effectively amplifies the port count of M x N WSS.
  • This approach offers a significant advancement in expanding the capacity of optical switching nodes for future communication systems.
