In Memoriam

Bernard Leonard: May 13, 1960 – November 20, 2015

Every summer, CIAN hosts amazing teachers from around the country in Research Experience for Teachers (RET) programs, and each year they return to their schools to inspire and excite their students about Science, Technology, Engineering, and Math (STEM). We have had many RET teachers who excel as summer researchers and teachers, setting an example of superior work ethic and devotion to excellence; Bernard Leonard was one of these. A role model to his fellow teachers and all who knew him, Bernard participated in the Research in Optics for K-14 Educators and Teachers (ROKET) program during the summer of 2014, at the University of Arizona. Sadly, after bravely fighting cancer, Bernard passed away on November 20, 2015.

Bernard was an honorable husband and father of two children. He taught children on Arizona’s Hopi reservation, and although some of us knew him only shortly, it was obvious that he was proud of his heritage and his roles as husband, father, and teacher. He was kind, humorous, and giving.

On behalf of the Center for Integrated Access Networks and the 2014 fellow ROKET participants, our thoughts and condolences are with Bernard’s family.

Thank you for your example, Bernard. It will not be forgotten.


Words from fellow teachers and ROKET participants:

“Bernard Leonard, a true Diné man and a friend of many, was an educator participant in the Summer of 2014 CIAN-ROKET STEM opportunity at the University of Arizona. Bernard may have lost his battle to cancer, but his fight of educating indigenous students in promoting the sciences remains. He was well loved by those of his family and friends across the Navajo Nation and especially by the community and families of the Hopi Tribe as he gave his all in educating students who entered his class over the years. It is with honor and gratitude to have had the opportunity to have met Bernard and to call him friend.”  

Bernard was a dedicated teacher who wanted to bring more to his tribe and help the students to reach… higher academic standards by participating in scientific research and different activities to bring more ideas of engaging Native American students to STEM and learning. He will be missed and hopefully other teachers from his area would follow in his foot steps to learn to engage Native American students.”

“When talking to Bernard, I was always reminded that I was talking to a true leader; a Father, husband, teacher, and Native American role model. He did it all and made it seem possible. Bernard inspired me to take value in my teaching and to follow the path that feels right.”

My RET Experience @ Tuskegee

Why a summer at Tuskegee?

I am a 6th grade middle school science teacher from Greenville, South Carolina, at Greenville Early College, “Home of the Eagles”.  I wanted to be here at Tuskegee University; to observe and learn from Dr. Korivi and Dr. Jiang’s Microelectronics’ lab, in hopes of engaging my students this year.  My goal is to infuse aspects of the lab’s research in my projects planned for this school year.  What an experience thus far!

This lab has been full of invigorating activities and I have been absorbing ideas from the professors and engineering lab students.  One might conclude that 6th grade is too young to benefit from such an experience.  To the contrary…


Designing wave guides to control an optical path, which will result in my students’ use of diodes for their projects this year.


New materials for capacitors, where my students can look to the future for outerwear to charge their cellphones and iPods.

Real-time Optical Performance Monitoring Using Time-stretch Technology

Daniel Lam
Ph.D. Candidate
CIAN Graduate Student

Daniel Lam received a B.S. degree in Optical Sciences and Engineering from The University of Arizona in 2008, and a M.S. degree in Electrical Engineering from Stanford University in 2009.  His research has been focused on digital broadband linearization of optical links and performing high speed measurements using time stretch technology under the guidance of Professors Bahram Jalali and Asad M. Madni.  He is an engineer with Northrop Grumman Aerospace Systems since 2009.  He is also a recipient of the Northrop Grumman Aerospace Systems Fellowship.


With the rapid development of optical networks, optical performance monitoring (OPM) has become a necessity for managing high capacity optical transmission and switching systems.  The transmission capacity can be attained by utilizing amplitude, phase, and polarization of optical waves to send information at increasing data rates.  However at higher transmission rates, impairments in the link could affect the optical wave properties that would impact information capacity.  This in turn requires the implementation of high speed monitoring techniques to monitor degradation/faults in the system and to perform efficient, automated corrective actions in the optical fiber communication network.  The Time-Stretch Enhanced Recorder (TiSER) is capable of providing real-time, in-service, signal analysis for degradation/fault detection.  By generating eye diagrams in real-time, TiSER can provide valuable information on important performance parameters such as bit error rate, rise and fall times, timing jitter, and other optical impairments.  Rapid OPM techniques to measure and provide mean time to repair and mean time to failure is required for next generation agile networks.

Real Holography

Among the credits I was taking this fall at the University of Arizona was the lab course OPTI380A. This lab was a foray into the realm of physical optics. For this class we had a final project that included a final written report as well as a video report. The project had to investigate or showcase some aspect of physical optics. The video, which had to be under four minutes in length, had to effectively summarize the project.

My lab partner, Braden Smith, and I decided to look into real holography. The title of “real” indicates that we were going to make a hologram of a real object. As my bio indicates, I’ve been working with holograms for a while with CIAN. Our lab works with computational holograms, where a model from a computer is decomposed into many views that are then holographically recorded in our re-writable medium. I’ve always been interested in making a “real” hologram though. The idea interested Braden too, so we made it our project. I’ll let our video explain the rest. Check it out!

In the Lab with Janelle Shane


Sometimes our samples get visitors.

In most cases, they’re simply little flecks of dust that have settled to the surface of our chips.  Since most of the structures we’re making are so small, your average chunk of dust can be comparatively building-sized.

They usually scare the willies out of me when I’m zoomed into my structure, scanning the microscope across, and suddenly one of them looms into the field of view like a giant monster.   Continue reading
