A DWDM (Dense Wavelength Division Multiplexing) system is the technology of choice for many optical networking applications today. By using many different wavelengths of light to route data, these systems are more efficient, flexible and cost-effective to build, own and operate compared to single channel point-to-point links. By using EFFECT Photonics’ high-density electrical interconnect and packaging technology, the Optical-System-on-Chip is assembled for volume manufacture at low cost.


One of the key challenges with DWDM technology is the need for as many optical light sources, modulators and detectors as there are channels in a system. Building and managing these using conventional discrete fiber optic components, linecards, AWG (Arrayed Waveguide) multiplexers and rackmount channel monitors quickly becomes prohibitively expensive.

As the channel count increases, so does the physical space in which to house the equipment and power consumption. The key enabling technology for DWDM systems at the edge of the network is photonic integration of components within a single chip and being able to produce these in volume with high yield at low cost. This requires a change in the way InP chips are designed, tested, and packaged, which is where EFFECT Photonics comes in

EFFECT Photonics is able to integrate the following optical functions all within a single InP chip:

  • Tunable laser sources
  • Arrayed Waveguide Grating multiplexers (AWG)
  • High Speed Detectors (PDs)
  • High Speed Modulators, including single or multi-stage Mach-Zehnder Modulators (MZM/MZI)
  • Power taps and splitters
  • Channel Monitoring
