Programmable Photonic Logic Array Based on Micro-Ring Resonators and All-Optical Modulation.

Area of Science:

• Photonics
• Optical Computing
• Integrated Circuits

Background:

• All-optical computing offers rapid computation using photons but lacks programmable designs.
• Progress in optical logic computing is hindered by the absence of functional, reconfigurable architectures.

Purpose of the Study:

• To design and propose a programmable photonic logic array for all-optical computing.
• To realize a complete set of reconfigurable all-optical logic functions using on-chip photonic devices.

Main Methods:

• Utilized micro-ring resonators and other on-chip photonic devices.
• Implemented basic (NOT, AND, OR) and combined (XOR, XNOR) logic functions.
• Employed two independent wavelengths for logic levels to minimize signal crosstalk.

Main Results:

• Demonstrated a programmable photonic logic array capable of multifunctional logic computation.
• Achieved multi-level cascading of structurally similar logic units for large-scale integration.
• Verified effectiveness and feasibility through simulations using the INTERCONNECT simulator.

Conclusions:

• The proposed architecture enables reconfigurable all-optical logic computation.
• The design effectively reduces signal crosstalk and dependence on optical signal strength.
• This work advances the development of large-scale, multifunctional photonic logic arrays.
