Photonic Architect, Temp

We are hiring a temporary employee at the PhD level for our Photonics Architecture team at Lightmatter! We are an optical interconnects company enabling the next generation of power efficient AI datacenters. With an increasingly large number of processor chips needing to be networked together to support the growing demands of AI, Lightmatter is creating engines that send data between processors using photons instead of electrons. Optical interconnections enable energy-efficient and high-speed communication links between the processors. 

Responsibilities 

• You will be part of the Passage transceiver product architecture team, focused on Photonic Architecture. 
• You will focus on the interaction between photonic effects and the performance of SerDes, drivers and TIAs. You will find creative solutions to maintain excellent error rates in our optical communications products, at ever-increasing throughput and density. 
• You will simulate end to end optical links, focusing on detailed optical effects such as fiber polarization, optical reflections, and thermal dynamics in silicon photonic structures. You will collaborate with our test team, to run remote testing on Lightmatter hardware, including SerDes, high-speed analog, and photonic chips. You will define test plans, and correlate test results with your simulations. 

Qualifications 

• Pursuing a PhD in Photonics, Optics, or Electrical Engineering with a specialization in optical communications. 
• Experience with optical link simulations in commercial tools such as VPIphotonics, Matlab, Virtuoso or ADS. 
• Highly motivated to learn about commercial applications of silicon photonics and optical communications. 
• Courses at the undergraduate and graduate level in electromagnetics (wave propagation, guided waves), semiconductor devices, semiconductor physics, optics, scientific computing, numerical methods, signals and systems, statistics, thermal physics, analog electronics. 
• Experience with Python programming. 
• Understanding of data collection and analysis. 
• Excellent oral and written communication skills. 

This role is located in Lightmatter’s Toronto office.
