What are the responsibilities and job description for the Postdoctoral Researcher position at UCLA?

Postdoctoral Researcher Position in Fiber Lasers and Frequency Combs University of California, Los Angeles (UCLA) The Quantum Light-Matter Cooperative (QLMC) is seeking a highly motivated and skilled postdoctoral researcher (or postdoc-equivalent) to join our team at UCLA. The successful candidate will work on cutting-edge research involving advanced photonic systems, with a focus on fiber lasers, frequency combs, and their applications in precision measurement and quantum technologies.

Key Responsibilities:
• Design, develop, and optimize fiber-based and solid-state laser systems.
• Investigate and implement frequency comb generation and stabilization techniques.
• Explore novel approaches for low phase-noise density performance and carrier-envelope phase (CEP) locking in multi-channel systems.
• Collaborate with a multidisciplinary team to advance the state-of-the-art in photonic entanglement and quantum state manipulation.
• Publish research findings in high-impact journals and present at leading conferences.

Required Qualifications:
• Ph.D. in Physics, Electrical Engineering, Optics, or a related field.
• U.S. citizenship or permanent residency.
• Expertise in fiber lasers, frequency combs, and nonlinear optics.
• Strong experimental skills in photonics, including experience with laser stabilization, phase noise characterization, and quantum state manipulation.
• Familiarity with integrated photonic platforms and hybrid photonic systems is a plus.
• Proficiency in data analysis and computational tools for modeling photonic systems.
• Excellent written and verbal communication skills.

Desired Qualifications:
• Experience with entanglement generation and characterization in photonic systems.
• Knowledge of quantum optics and quantum information science.
• Background in telecom-band photonics and frequency-bin entanglement.
• Demonstrated ability to work independently and collaboratively in a fastpaced research environment.

About the Project: The research involves advancing the frontiers of photonic entanglement and precision measurement using state-of-the-art laser and frequency comb technologies. The project builds on recent breakthroughs in fiber-based and solidstate systems, with a focus on achieving high-fidelity, low-phase-noise performance across multiple channels. The successful candidate will have the opportunity to explore innovative approaches and contribute to the development of nextgeneration photonic instruments.

Application Process: Interested candidates should submit the following materials to the PI directly (scarbajo@ucla.edu) with the subject line "Postdoc Application – Fiber Lasers and Frequency Combs" and
1. A cover letter detailing your research experience and interest in the position.
2. A current CV, including a list of publications.
3. Contact information for three professional references.

Review of applications will begin immediately and continue until the position is filled.

The expected start date is flexible, with a preference for candidates available to begin within the next 3 months. DURATION: Minimum of a 2-year contract with a possible extension to 3 years total.

UCLA is an equal opportunity employer and welcomes applications from individuals of all backgrounds.
