About the role

  • This role will lead Neurophos' C-band high-power laser development programs.
  • This is a senior position requiring deep technical expertise in laser physics and the ability to drive complex photonic device development from architecture through productization.
  • They must be skilled at planning around long foundry lead times, structuring work to minimize re-spins, and managing vendor relationships at the epi and process-spec levels.

Responsibilities

  • Lead the design, development, and optimization of high-power laser systems operating in the C-band (1550 nm).
  • Experience developing erbium-doped fiber amplifier or waveguide amplifier laser systems.
  • Define and drive laser system configurations to achieve high output power targets with high coherence, narrow linewidth, and low noise.
  • For injection-locked systems, own the locking-range analysis, injected-power-ratio optimization, and stability-margin assessment across temperature and aging conditions
  • define feedback and control requirements for maintaining lock, and validate that the electronics solutions meet system-level specs.
  • Own system-level trade studies covering optical output power, coherence length, linewidth, RIN, SMSR, locking bandwidth, and wavelength stability across operating conditions.
  • Develop and validate device and system models to predict performance and guide design decisions through simulation platforms such as Lumerical, VPIphotonics, PICS3D, or equivalent.
  • Build, lead, and mentor a multidisciplinary laser engineering team spanning laser physics, photonic integration, packaging, and test.
  • Drive program execution across in-house engineering teams and external foundry and packaging partners
  • Lead design reviews, root-cause failure analyses, and risk mitigation planning for laser subsystems.

Requirements

  • 12+ years of progressive experience in laser and photonic device/system development, with at least 4 years in technical leadership or management roles.
  • Demonstrated hands-on experience with high-power laser development, including design, foundry engagement, device characterization, and qualification.
  • Deep expertise in C-band laser physics and system integration, including high-output-power architectures targeting narrow linewidth, low RIN, and high SMSR.
  • Proficiency with test and measurement systems relevant to coherent laser characterization: OSA, frequency/phase noise analyzer, self-heterodyne linewidth measurement, LIV, locking range characterization, and BERT.
  • The candidate must have hands-on experience driving laser hardware development programs spanning multiple interdependent subsystems.
  • Ph.D. in Photonics, Electrical Engineering, Applied Physics, or a closely related field. M.S. with extensive industry experience will be considered.
  • Proven track record developing and qualifying EDWA/EDFA configurations and/or injection-locked laser systems for high-power single-wavelength output (e.g., >300 mW fiber-coupled).
  • System-level understanding of injection-locking dynamics: locking bandwidth and its asymmetry, linewidth enhancement factor (α-factor) and its role in frequency pulling and phase noise, master-slave optical path design, and stability under varying temperature and drive conditions.
  • Ability to define feedback and control requirements for maintaining injection locking over temperature and aging, and to validate that electronics solutions meet system-level specs - without necessarily designing the control loop directly.
  • Understanding of behavior in coherent systems: phase noise contribution, gain saturation, ASE management, back-reflection risks, and polarization sensitivity - and how to design around these constraints at the system level.
  • Strong background in optical system-level design: fiber coupling, higher power laser packaging.
  • This is an opportunity to play a pivotal role in an innovative startup redefining the future of AI hardware. Work on game-changing technology at the intersection of photonics and AI as part of a collaborative, brilliant team.
