研究目的
Investigating the use of integrated photonic filters for flexible analog-based mobile fronthauling to support wavelength selectivity, reconfigurability, and advanced signal processing at the optical edge.
研究成果
The proposed WDM-enabled flexible mobile fronthauling architecture, based on integrated analog optics and silicon-based filtering implementations, shows significant potential for supporting flexible-grid MFH architectures with Gbaud rate 16-QAM modulated radio. The experimental demonstration of dispersion-induced transmission penalty mitigation through analog photonic processing highlights the practical applicability of the proposed solutions in 5G deployment scenarios.
研究不足
The study is limited by the experimental setup's reliance on specific components like the MZM and SOI-based filters, and the practical challenges of scaling the proposed architecture for ultra-dense 5G topologies.
1：Experimental Design and Method Selection:
The study employs a WDM-enabled analog mobile fronthaul architecture utilizing silicon photonics-based filtering elements for flexible wavelength assignment and signal processing.
2：Sample Selection and Data Sources:
The experiment uses four Continuous Wave (CW) lasers to form a Dense WDM (DWDM) grid with 50-GHz channel spacing.
3：List of Experimental Equipment and Materials:
Includes a single-drive MZM biased at the quadrature point, SOI-based 2nd order ring resonator geometries, and a typical photoreceiver module.
4：Experimental Procedures and Operational Workflow:
Involves tuning the spectral passband of the integrated optical filter to select different optical carriers after transmission through a 2-km long SSMF fiber link.
5：Data Analysis Methods:
Performance evaluation is conducted using constellation diagrams and Error Vector Magnitude (EVM) measurements.
