This study introduces a tunable optical time-division multiplexing (OTDM) system using slow light, significantly improving performance and reducing power penalties. The novel approach enables variable bit-rate OTDM, enhancing data stream efficiency.

Area of Science:

Photonics and Optical Communications
Signal Processing

Background:

Conventional fiber-based optical time-division multiplexing (OTDM) systems often use fixed multiplexers, limiting flexibility.
Achieving tunable delay lines for OTDM is crucial for enhancing system performance and accommodating variable data rates.

Purpose of the Study:

To conceptually compare slow-light-based tunable OTDM with conventional fixed OTDM multiplexers.
To experimentally demonstrate a continuously controllable OTDM system using slow light for tunable optical delay.

Main Methods:

Utilized broadband stimulated Brillouin scattering (SBS)-based slow light as a tunable optical delay line.
Demonstrated continuous manipulation of signal time slots by up to 75 ps.
Implemented variable-bit-rate OTDM by dynamically adjusting the slow-light delay.

Main Results:

Achieved a 9-dB reduction in power penalty for the multiplexed data stream due to slow light tunability.
Successfully demonstrated continuous time slot manipulation for two 2.5-Gb/s return-to-zero (RZ) signals.
Showcased efficient two-by-one OTDM of three different input data streams at varying bit rates (2.5 Gb/s, 2.67 Gb/s, and 5 Gb/s).

Conclusions:

Slow-light-based tunable OTDM offers significant advantages over conventional fixed OTDM.
Continuous slow light tunability enhances OTDM system performance and enables variable bit-rate operation.
The demonstrated system provides a flexible and efficient solution for advanced optical communication networks.
