Summary
This study presents a flexible and efficient theoretical model for simulating integrated photonic devices like sampled grating distributed Bragg reflector (SGDBR) lasers with semiconductor optical amplifiers (SOA) and Mach-Zehnder (MZ) modulators.
Area of Science:
- Photonics
- Semiconductor devices
- Optical engineering
Background:
- Integrated photonic circuits (PICs) require accurate simulation tools.
- Existing models may lack flexibility or efficiency for complex devices.
Purpose of the Study:
- To develop a novel theoretical model for simulating SGDBR lasers integrated with SOA and MZ modulators.
- To enhance the efficiency and flexibility of photonic device simulation.
Main Methods:
- Utilizing the time-domain traveling wave (TDTW) method for active and SOA sections.
- Employing Transfer-Matrix Method (TMM) and Beam Propagation Method (BPM) for spectral properties, with digital filter transformation.
- Incorporating nonuniform carrier-dependent gain and refractive index via Effective Bloch Equations (EBE).
Main Results:
- Successfully simulated the static and modulation performances of the integrated device.
- Demonstrated the model's flexibility and efficiency compared to full time-domain methods.
