Travel: Up to 5% Job ID: 1703 The Role: As a PIC Laser Scientist, you will bridge the gap between fundamental optical physics and scalable chip-scale technology. You will be responsible for the end-to-end development of custom laser systems, evolving them from initial concept through system-level integration. Your work will primarily focus on architecting the transition of high-precision frequency combs and ultra-low-noise systems from traditional discrete components to advanced Photonic Integrated Circuit (PIC) platforms.

By combining hands-on benchtop metrology with sophisticated chip-level simulation, you will drive the innovation of laser architectures for next-generation quantum timing, atomic clocks, and inertial sensors.

Responsibilities

: System Architecture: Develop custom laser systems from fiber-based oscillators to integrated chip-scale architectures. PIC Design Simulation: Design and simulate PIC layouts optimized for high-Q micro-resonators and dispersion-engineered nonlinear optics using materials like SiN, TFLN, and Tantala. Translation Integration: Architect the migration of frequency combs and low-noise systems from discrete fiber/free-space components to PIC platforms.

Assembly Characterization: Build and characterize conventional systems, including fiber spooling, MOPA configurations, and discrete nonlinear conversion stages. Precision Metrology: Perform rigorous characterization of frequency noise, phase noise, and Allan deviation at both the benchtop and chip levels. Frequency Stabilization: Develop testing protocols for stabilization architectures, including PDH locking and f-2f self-referencing.

Cross-Functional Collaboration: Partner with hardware teams to integrate laser systems into atomic clocks and quantum timing sensors.

Requirements

: 3+ years of professional experience working with ultra-stable cavities, frequency combs, or atomic clocks. PhD in Physics, Electrical Engineering, or a related field with a focus on atomic/optical physics, frequency metrology, or integrated photonics. S.
