Postdoctoral Opportunity – THz Sensor Technology

We are seeking qualified and talented postdoctoral candidates to join our team in summer 2018 to work on a project to develop uncooled THz sensors for space applications.  The selected individual will work on a NASA-supported program to develop an uncooled THz heterodyne sensor based on the photo‐thermo‐electric effect in graphene. The proposed sensor is being studied for potential use in in future space flight missions to the icy moons of Jupiter and Saturn, which seek to assess the presence of pre-biotic organic molecules in the atmospheres of these moons. This experimental project will include lithographic processing of graphene terahertz devices, measurements of the THz response, noise and bandwidth characterization, as well as antenna design and modeling.

Essential skills and experience sought:

  • PhD awarded (or expected) in Applied Physics, Engineering, Physics, or related field
  • Excellent communication skills (in writing and speaking)
  • Cleanroom fabrication experience (photolithography, e-beam lithography, etching, deposition)
  • Experience with DC and microwave electrical characterization of devices

Desirable skills include:

  • Numerical modeling, design, and optimization of THz and microwave devices (HFSS, CST, Comsol)
  • Processing and characterization of 2D materials
  • Experience with THz measurements and instrumentation (bolometers, mixers, FTIR)
  • Microwave measurements and instrumentation (spectrum/network analyzers, noise metrology)

Interested applicants should email Thomas E. Murphy (tem@umd.edu) or H. Dennis Drew (hdrew@umd.edu) with a CV and list of potential references.

The University of Maryland is located in the Washington DC Metropolitan area, which is not only a great place to live, but our proximity to many nearby collaborators, universities, government laboratories, and sponsors makes it an ideal place for a young scientist to launch a career. The University also offers excellent benefits and competitive salary.

Postdoctoral Opportunity in Integrated Photonics

We are currently seeking talented and motivated postdoctoral candidates to join our group at the University of Maryland, working at the Laboratory for Physical Sciences on integrated photonic devices. Our laboratory offers state-of-the-art research facilities, including access to nanofabrication facilities at LPS and through the Maryland Nanocenter, optical waveguide measurement, and high-speed photonic characterization tools. The successful applicant will participate in existing projects and contribute to advancing our research program by investigating novel concepts and devices and proposing new ideas.

Essential skills and experience sought:

  • PhD awarded (or expected) in Applied Physics, Engineering, Physics, or related field
  • Excellent communication skills (in writing and speaking)
  • Basic cleanroom fabrication experience (lithography, dry etching, thermal processing, etc.)
  • Experience with measurement automation and data acquisition

Desirable skills include:

  • Nanofabrication and nanocharacterization experience (electron-beam lithography, AFM, etc.)
  • Hands-on experience conducting optical device measurements including integrated photonic systems
  • Numerical simulation of integrated photonic systems (FDTD, FEM)
  • Experience performing measurements in a cryostat

The University of Maryland and the Laboratory for Physical Sciences are located in the Washington DC Metropolitan area, which is not only a great place to live, but our proximity to many nearby collaborators, universities, government laboratories, and sponsors makes it an ideal place for a young scientist to launch a career. The University also offers good benefits and competitive salary.

Starting date: (Negotiable), ideally before August 31, 2018

To apply, please send your curriculum vitae, along with the names and contact information of three potential references to photonicspostdoc@umd.edu

U.S. citizenship is preferred.

Measuring, comparing, and quantifying optical random number generators

Check out our recent invited perspectives article entitled “Recommendations and illustrations for the evaluation of photonic random number generators,” which was published this week in APL Photonics, and featured in an AIP Scilight piece.  We offer a fresh perspective on the rapidly developing technology of optical random number generation, and offer our recommendations for how to measure and extract entropy from optical processes.

Welcome to Nathan Super

Nathan Super joins the lab this summer through the NSF-sponsored TREND program.  Nathan is currently pursuing his bachelor’s degree in Physics at William and Mary College.

Amir Ali Ahmadi wins Sloan Foundation Fellowship

Prof. Amir Ali Ahmadi (Princeton) was selected this year as one of only 126 individuals in the US to win an Alfred P. Sloan Foundation Fellowship. Amir was an undergraduate researcher in our laboratory in 2005, and although he is currently studying operations research and financial engineering, as a Maryland undergraduate student he published a paper in the Journal of Lightwave Technology and presented his work at the Optical Fiber Communications conference.

PRL Editor’s Suggestion: Continuous-Wave Photomixing in Graphene

Our paper entitled “Tunable Ultrafast Thermal Relaxation in Graphene Measured by Continuous-Wave Photomixing” was published this week in Phys. Rev. Lett. and was highlighted as an Editor’s Suggestion. Only about one in six PRL papers are so highlighted, based on work that is judged to be particularly important, interesting, and well written.
