Multi-channel collision-free reception for optical interconnects

Area of Science:

• Optoelectronics
• Optical Communication Networks
• Information Theory

Background:

• Optical interconnects are crucial for high-speed data transfer.
• Simultaneous reception of multiple wavelengths is a key challenge.
• Existing schemes often face limitations in collision-free operation.

Purpose of the Study:

• To propose a novel multi-channel reception scheme for optical interconnects.
• To enable collision-free, simultaneous reception of arbitrary wavelength sets.
• To reduce hardware complexity by using fewer receivers and fixed filters.

Main Methods:

• Design of a multi-channel reception scheme utilizing fixed-wavelength filters.
• Application of error-control coding theory for filter design.
• Experimental validation of reception units with up to four collision-free channels.

Main Results:

• Demonstration of a collision-free multi-channel reception scheme.
• Successful simultaneous reception of arbitrary wavelength sets.
• Validation of the scheme's feasibility through experimental units.

Conclusions:

• The proposed scheme offers an efficient solution for optical interconnects.
• Error-control coding provides a robust framework for designing optical filters.
• The experimental results confirm the practical viability of the multi-channel reception approach.
