IOU REU: 2017 Program Summary

Every summer, CIAN hosts undergraduate students for the Integrated Optics for Undergraduates (IOU) Research Experience for Undergraduates (REU) program. This summer CIAN hosted four talented and successful students to participate in innovative research across CIAN campuses nationwide. Following is a summary of these students’ experiences and more information about the program.

Columbia

Aneek James, an electrical engineering student from the University of Georgia performed research on Construction of a Fiber Array-Centered Silicon Photonic Chip Prober. His Mentor was Dr. Keren Bergman.

Aneek working on his research project.

Project Abstract:

Two-fiber stage probers are limited in stability, cost of required actuators, and inability to run parallel tests on the I/ O ports(e.g. cross talk experiments). In an effort to address these issues, a fiber array-based prober was developed to facilitate efficient testing of silicon photonic chips.


Berkeley

Jazz Pouls, an electrical engineering and computer science major from the University of California Berkeley performed research on Accelerated High Precision 3D Imaging with FMCW Lidar. His mentor was Dr. Ming Wu.

Project Abstract:

Frequency Modulated Continuous Wave Lidar (FMCW)

  • Galvo mirrors to scan laser across target
  • Interferometry to determine target’s distance
  • Applications: driverless cars, robotics, manufacturing
    • These applications need high resolution and speed
    • Current resolution is good: <1mm resolution at ~10m distance
    • Our current system is slow: a 100×100 point scan takes ~10 min
    • Goal: Increase speed, ideally to video frame rate (30 fps)

NSU

William (Trey) Rauh, an engineering major from the Tidewater Community College completed his project on Optical Triplexer Design. Dr. Demetris Geddis was his mentor.

Project Abstract:

  • Optical Triplexers are utilized in the creation of optical networks. These devices are used to send and recieve multiple wavelengths of light in the same fiber optic cable.
  • Incoming optical pulses are converted to electric signals via photodetectors.
  • Outgoing electrical transmissions are emitted by VCSEL (Vertical Cavity Surface Emitting Laser).
  • Ultimately, the triplexer serves as a device for converting optical pulses to electrical signals, and vice versa.

 

Jeffrey Smith, an engineering student from Thomas Nelson Community College performed research on Design and Simulation of Reciever and Transmitter Circuits for Optical Triplexers. Dr. Demetris Geddis also mentored him.

Project Abstract:

The goal was to design and simulate receiver and transmitter circuits for optical triplexer. Fiber networks are so cost effective that this new triplexer build might be a more cost efficient way to open a catalyst of data centers.

I’m personally motivated by the children whom live in poverty stricken communities or those secluded rural areas where fiber coverage isn’t offered. Providers only render these resources to the more prominent economies. The motivation for this research for me is giving people the tools they need but were never offered, so that they may transform their minds.
