This study introduces a silicon micro-ring modulator (MRM) with a tunable two-point coupling scheme to correct fabrication errors. This innovation enhances MRM commercialization by allowing post-fabrication tuning of wavelength and bandwidth for improved yields in DWDM applications.

Area of Science:

Photonics
Integrated Optics
Semiconductor Devices

Background:

Fabrication errors impede the widespread adoption of silicon micro-ring modulators (MRMs).
Post-fabrication correction of spectral features is crucial for the commercial viability of MRMs.
Existing MRMs often lack the tunability required to compensate for manufacturing imperfections.

Purpose of the Study:

To demonstrate a novel micro-ring modulator (MRM) design enabling post-fabrication spectral correction.
To address the challenge of fabrication errors in silicon MRMs for improved commercial yields.
To validate the performance of the tunable MRM for high-speed data modulation and DWDM compatibility.

Main Methods:

Development of a micro-ring modulator (MRM) featuring a tunable two-point coupling scheme.

Characterization of the MRM's spectral tuning capabilities for wavelength and optical bandwidth adjustment.

Testing of the MRM's modulation performance using Non-Return-to-Zero (NRZ) and Pulse Amplitude Modulation-4 (PAM-4) signals.

Main Results:

The proposed MRM maintains a compact footprint (60 µm × 45 µm).
Tunable coupling allows for precise adjustment of operating wavelength and optical bandwidth/extinction ratio.
Successful NRZ modulation up to 28 Gb/s and PAM-4 modulation up to 19.9 Gb/s were demonstrated.
The device preserves the microring's free-spectral range (FSR), ensuring DWDM compatibility.

Conclusions:

The tunable two-point coupling scheme effectively compensates for fabrication errors in silicon MRMs.
This approach significantly improves the potential yield and commercialization prospects of MRMs.
The demonstrated MRM is suitable for configurable, high-bandwidth Dense Wavelength Division Multiplexing (DWDM) systems.
