Optical Engineer

Responsibilities:

1. Select, drive and frequency-stabilize laser sources (narrow-linewidth / tunable / mode-locked) to supply pump and signal light for photonic quantum chips.
2. Lead design & optimization of nonlinear processes (SPDC, FWM, SHG) to improve entangled-source / squeezed-state generation and frequency-conversion efficiency.
3. Define laser–chip coupling schemes (fiber / facet / grating) with the chip team; solve alignment, mode-matching and thermal issues.
4. Build precision optical test benches; characterize lasers and nonlinear processes; resolve system noise and parasitic effects.

Requirements:

1. Master's or above (PhD preferred) in Optics, Physics, Photonics, or related.
2. 3+ years in laser R&D or nonlinear optics with independent optical-system build experience.
3. Deep knowledge of laser physics & stabilization (e.g. PDH), mode-locking; nonlinear optics & quasi-phase-matching; fiber/spatial coupling, polarization control, weak-signal detection; Zemax/OpticStudio or Python/MATLAB/LabVIEW.
4. Ability to solve complex experimental problems; teamwork and English literature reading.
5. Plus: quantum light sources (entanglement / single-photon), optical frequency combs; fiber amplifiers / high-power lasers; chip packaging & opto-mechanical integration.
