Senior Photonics Engineer – Homodyne detection

Hands-on experimental optics lab experience, with knowledge in integrated optics & fibre optics, locking optical interferometers & noise characterization.

Direct experience with homodyne detection of optical signals.

Experience with pulsed homodyne detection is preferred, but not required.

Working familiarity with opto-electronic detectors, transimpedance amplifiers; sound understanding of common RF electronics & electro-optic modulator concepts.

in Quantum Optics, Photonics, AMO, Electrical Engineering or a closely related field.

Greater than 4 years of experience in any of: quantum computing (particularly in optical quantum computing); thin-film lithium niobate modulators; or waveguide-integrated photodiodes.

We are seeking a Senior Photonic Engineer – Integrated Homodyne to participate in designing, developing and experimentally validating cutting-edge photonic systems.

You will be working with photonic chips that include networks of high-speed electro-optic modulators and integrated balanced homodyne detectors, with a particular focus on high-efficiency pulsed homodyne detection and pulsed quantum homodyne tomography.

Design, build and upgrade complex optical laboratory experiments to characterize the performance of photonic integrated chips with electro-optic elements, using continuous-wave and pulsed laser light.

Characterize and benchmark the performance of integrated balanced homodyne detectors for pulsed signals, with bandwidths in the hundreds of MHz regime.

Design and build new characterization strategies as needed, to fit evolving optical/electrical requirements.

Measure figures of merit including detection efficiency, noise clearance, effective bandwidth, common-mode rejection, cross-talk etc.

Xanadu’s mission is to build quantum computers that are useful and available to people everywhere.

At Xanadu, we are learners, innovators, researchers, collaborators and problem solvers. We are creating something that has never been built before. What we are doing is extremely hard, the classic moon shot. Few people in their life will be able to be a part of something like this, where if we are successful, the technologies we develop will solve some of the world’s most challenging problems, and literally change the world. And that is something to be excited about!
