RANOVUS, with operations in Ottawa, Canada, Nuremberg, Germany, and San Jose, USA, is a solution provider for the next generation interconnects for the telecommunications and information technology industries. RANOVUS’ current disruptive portfolio includes Quantum Dot Multi‐Wavelength Laser technology and advanced digital and photonics integrated circuit technologies that are setting a new industry benchmark for the lowest power dissipation, size and cost for the next generation of optical interconnect solutions.

The company is currently seeking candidates for three internships, to begin no later than January 2019. The candidates should be enrolled in a Ph.D., M.Sc. or M.A.Sc. research degree with a thesis topic which has at least partial alignment with one of the post descriptions below:

1. Silicon photonic device characterization, simulation and design
This position will require measurement of optical devices via both grating and edge‐coupling from optical fibers. Both DC and RF measurements will be performed including the acquisition of large signal data such as eye‐diagrams and determination of bit‐error rates. In addition to experimental work, the position requires optical device simulation and design such as mode‐solving, FDTD, BPM and eigenmode expansion. Experience with chip layout software would be a significant asset.

2. Laser measurement, simulation and design
The successful candidate will measure the performance characteristics of leading edge quantum dot laser structures. Optical measurements will be performed at both low‐speed and at frequencies in the RF range. Experience writing GPIB control algorithms and automating measurement would be very useful. Depending on skills and interest, some activities may involve coupling lasers to photonic integrated circuits.

3. Opto‐electronic packaging
The Advanced Optoelectronic Packaging Design group within RANOVUS, represents one of the key elements of product development for next generation all optical datacenter networks. The Optoelectronic Packaging intern will work within a multi‐disciplinary packaging team to assist in the development of state of the art optoelectronic products. The candidate will work closely with RF, optical, and process engineers within the packaging team to help successfully develop and implement advanced micro/optoelectronic packages and subassemblies. The position involves supporting prototype builds, assisting in the setup of active and passive optical alignment and optical verification stations; writing code for motorized station control and automation; data collection; optical experimental setup and metrology.

Each of the three internships will typically last for four months and will require the candidate to relocate to RANOVUS’ headquarters in Ottawa. Each candidate must have the required legal status within Canada to allow employment as an intern.
