Background:

  • Wavelength Division Multiplexing Passive Optical Networks (WDM-PON) require efficient driver circuits for electro-absorption modulators (EAMs).
  • Existing EAM driver ICs often face challenges with high power consumption, limiting network scalability and operational efficiency.

Purpose of the Study:

  • To develop and present an ultra-low power Silicon-Germanium Bipolar Complementary Metal-Oxide-Semiconductor (SiGe BiCMOS) integrated circuit (IC).
  • To enable high-speed driving of a 10-channel EAM array for advanced WDM-PON applications.

Main Methods:

  • Design and fabrication of a SiGe BiCMOS IC.
  • Characterization of the driver array's performance at 113Gb/s.

Main Results:

  • The EAM driver array achieves an ultra-low power consumption of 2.2W (220mW per channel) with a 2.5Vpp output swing.
  • This represents a 50% reduction in power consumption compared to the state-of-the-art.
  • Configurable output swing (1.5-3.0Vpp) and bias (0.75-2.15V) were demonstrated.

Conclusions:

  • The developed SiGe BiCMOS IC offers a significant advancement in power efficiency for EAM drivers in WDM-PON systems.
  • The configurable nature of the driver enhances its applicability across various WDM-PON architectures.
  • This technology paves the way for more energy-efficient and scalable optical access networks.
