Postdoctoral Associate

Requisition Number:

21999

Location:

Boulder, Colorado

Employment Type:

Research Faculty

Schedule:

Full-Time

Date published:

23-Oct-2019

Job Summary

The Waveform Metrology group in the Communications Technology Laboratory at NIST is starting an effort to build a new ultrafast laser based electro-optic sampling (EOS) system for the time and frequency characterization of electrical signals, with the goal of providing a measurement service for instrumentation used with high-speed communication systems.  The new system will use dual frequency comb (DFC) source, two mode-locked fiber lasers with a slight difference in repetition rate.  The measurement is done in an asynchronous manner, where the delay between pulses is set by the repetition rate difference, allowing for one pulse to scan through the other without the need of a mechanical delay line.  Furthermore, the DFC-EOS method improves the spectral resolution to the repetition rate of laser (100 MHz), thus freeing the resolution from the physical length of a delay line.

Who We Are

The Professional Research Experience Program (PREP) is a special partnership between the National Institute of Standards and Technology (NIST) and the University of Boulder.  PREP provides research opportunities to CU undergraduate and graduate students, as well as researchers with a Bachelor's, Master's, or PhD in NIST labs to gain research experience alongside NIST scientists.

What Your Key Responsibilities Will Be

  • Characterize and test the optical and electrical properties of a mode-locked fiber laser system.
  • Locking a frequency comb to an RF or optical reference.
  • Construct an electro-optics sampling system using a DFC system.
  • Work as a member of a collaborative, interdisciplinary team.
  • Provide technical input to research problems which have been recognized as critical obstacles to progress in areas of exceptional interest.
  • Prepare and review journal publications.
  • Attend research conferences and present technical results.
  • May also be responsible for mentoring any graduate or undergraduate students working on the project.

What We Can Offer

The annual salary range for this position is market-based, highly competitive, and will be based upon relevant background and experience. 

Benefits

The University of Colorado offers excellent benefits, including medical, dental, retirement, paid time off, tuition benefit and ECO Pass. The University of Colorado Boulder is one of the largest employers in Boulder County and offers an inspiring higher education environment. Learn more about the University of Colorado Boulder.
