DWDM optical System-on-Chip (SoC) technology

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.

As the channel count increases, the physical space in which the equipment is housed gets larger and the power consumption increases as well. The key enablers for DWDM systems at the edge of the network is photonics 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 indium phosphide (InP) chips are designed, tested, and packaged, which is where EFFECT Photonics comes in.


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.

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

  • Tunable laser sources
  • AWG multiplexers
  • High-speed detectors (photodiodes)
  • High-speed modulators, including single- or multi-stage Mach-Zehnder modulators/interferometers (MZMs/MZIs)
  • Power taps and splitters
  • Channel Monitoring

NarroWave Technology-Enabled SFP+ Modules

EFFECT Photonics’ new NarroWave technology is a new feature that allows customers to monitor and control remote SFP+ modules from the central office without making any hardware or software changes in the field. NarroWave is agnostic of vendor equipment, data rate or the protocol of the in-band traffic. The host at the central office can access the remote digital diagnostics and monitoring by reading dedicated memory pages of the local SFP+, which are a mirror of the host device. This feature can also be used to send commands to a remote device, which enables use-cases such as automatic tuning and automatic power balancing. This makes EFFECT’s SFP+ modules a powerful asset in the toolkit of any telecom provider looking to dynamically control and monitor its telecommunication network.

Chip Engineering Manager

“We grew together with EFFECT Photonics, I started as an engineer and I got promoted to engineering manager of a group of 12 people”

What is the most interesting aspect of working at EFFECT Photonics? And what about your job specifically?

My motivation to come to EFFECT Photonics was to shift from an academic to a business environment. At a company you can focus as a team on a single objective. Instead of being scattered over multiple research areas, all people at EFFECT Photonics focus on a single project and goal. Coming from a PhD where I was the only Dutch candidate, managing a multi-cultural team is no big change for me. I do operate from a Dutch perspective, my team gets the impression that Dutch companies are fairly flat. Although there is a formal management hierarchy, the work environment is very open and friendly. I try to be as approachable as possible. Decisions are the result of discussions with the team and weighing that against other business requirements. As a manager, I can lean on a strong technical background to be able to make correct decisions and guide the team to the best approaches. As my team is quite big, members are expected to be quite independent. This creates a lot of independence within people’s roles.

What advice would you give to someone who is planning to apply at EFFECT Photonics?

What me and my team do, is central to the company. It is a nice position to be in. It means we have a lot of interaction and dependency. Because of this central role, expectations are high and there is pressure to get good results. We deal with this by working very precisely and thoroughly preparing any designs we send out for manufacture. I feel that there is a very solution-focused environment here at EFFECT Photonics, where taking initiative is rewarded. I’d say join us if you want to be a part of a team developing high-tech solutions for the telecommunications industry.

Describe in 3 words what your job is all about.

Challenges, learning, advancement

I joined EFFECT Photonics during its early beginnings in 2014. I had just finished my PhD and was looking for work. I knew the co-founders of the company via the Technical University of Eindhoven and I was able to help them out with some odd jobs here and there. My role initially was very undefined as the company was in its early stages. When the company got its first round of funding, I was brought on for a full-time position. I really grew with the company, initially as an engineer and then I became an engineering manager, where I came to lead an ever-expanding team. I still love the engineering work itself, but managing a team of people is also very rewarding. EFFECT Photonics is a very high-tech environment, there is always a lot of cool stuff going on. Few companies do what we are doing. We are really trying to bring about lower cost solutions, which does come with engineering challenges. We have a very skilled and talented team, and I have full confidence that we will solve these challenges.

What is your biggest highlight of working here so far?

I think for me it is seeing the level of commitment from the team. Every one is prepared to go the extra mile in order to get good results. Additionally, there is a lot of excitement here, there is a buzz when you get new results. The wafer has only been in the office for an hour and you already get messages from colleagues eagerly waiting for the results. It’s this buzz that is a real highlight for me.
