An Interview With the Professor At the back of CU Boulder’s Energetic Optical Gadgets Specialization

Uncover how photonics and semiconductors are impacting the entirety from transportation to healthcare and learn the way you’ll be able to get started getting ready for a occupation in electric engineering.

That is a thrilling time to be pursuing {an electrical} engineering level. Electric engineers are shaping the way forward for transportation, pioneering new approaches to healthcare, and addressing the present chip scarcity impacting international provide chains.

College of Colorado Boulder Professor Juliet Gopinath, PhD, helps construct the following era {of electrical} engineers via analysis taken with photonics and quantum engineering and educating on campus. Amongst many accomplishments, she has created the Energetic Optical Gadgets Specialization for the Grasp of Science in Electric Engineering on Coursera.

We spoke with Professor Gopinath just lately about her background, the MS-EE program, and her Energetic Optical Gadgets Specialization on Coursera.

Are you able to let us know just a little about your engineering background and why you selected to show on the College of Colorado Boulder?

I’m a fifth-generation engineer. I were considering science and math from a tender age, so I studied electric engineering on the College of Minnesota. In a while, I implemented to {the electrical} engineering program at Massachusetts Institute of Generation (MIT) and started my graduate paintings. At MIT, I had the risk to be a part of a world-renowned Ultrafast Optics workforce. I studied the dynamics of electrons and holes in semiconductors with mild, and I used to be blown away by way of how a lot you must be told.

After I graduated, I took a role on the MIT Lincoln Laboratory, the place I constructed high-power lasers, together with semiconductor lasers. In 2009, I had the chance to transport to the College of Colorado Boulder and sign up for the Electric, Laptop, and Power Engineering and Physics Departments.

What led you to create the Energetic Optical Gadgets Specialization on Coursera, and what sort of alternative does this program constitute for aspiring electric engineers? 

Once I joined CU-Boulder, I began educating a direction on Energetic Optical Gadgets—and truly fell in love with it. The fabric was once no longer simplest attention-grabbing, however helpful. When I used to be on sabbatical, a colleague approached me about striking those lessons on Coursera.

My dad is from India, and I do know I’m privileged to have had those instructional alternatives. Folks in different nations, particularly ladies, steadily don’t have the similar alternatives to take lessons in electric engineering or get right of entry to upper schooling. I sought after to place my categories on-line as my approach to give again and building up get right of entry to to those subjects.

What sort of background will have to scholars have in the event that they need to take this subsequent step on their occupation adventure?

As a way to learn about photonics, you wish to have to have taken an undergraduate elegance in electromagnetics. That is the core curriculum for each electric engineering and physics. It’s additionally extraordinarily useful if in case you have taken a fundamental Semiconductor Physics direction, corresponding to the only my colleague Professor Wounjhang Park has introduced on Coursera.

Are you able to percentage some ideas on why you’d counsel pursuing the MS-EE program as a basis for pro abilities?

The MS-EE program is an unbelievable alternative. You’ll earn your grasp’s with out leaving your front room. Schooling is figure, but it surely permits us to proceed to innovate and alter lives. If you have an interest in photonics and semiconductors, this Specialization is a good way to be informed the construction blocks that you’d want for a communications device or different optical device. 

Why are photonics and optics such vital subjects for long term electric engineers?

Photonics and optics truly contact each and every a part of your lifestyles—from the LiDAR far flung sensing used to watch herbal screw ups or lend a hand with self-driving automobiles, to retina scanning utilized in eye assessments. Whilst you cross to the grocery store and scan your merchandise at checkout, a laser is concerned. When you’re taking phase in a Zoom name, there’s an optical fiber that carries the dialogue and video. Lasers are even used for protection, corresponding to with standoff detection.

We’re listening to so much about electric engineering and lasers within the information in recent times. Do you suppose that is having an influence on hiring call for, and if that is so, why?

Lasers are used within the production of semiconductor chips. At the moment, there’s a world scarcity of chips this is impacting automotive production and extra. Discussions are going down about expanding this chip production in america. Finding out the physics of semiconductors and interplay with mild (optoelectronics) is very important. There’s a really extensive want for electric engineers with wisdom on this topic house.

What will have to scholars be expecting upon enrolling in this system?

The primary process the Specialization, Mild Emitting Diodes and Semiconductor Lasers, is for sure the hardest, however scholars can ask questions and have interaction with the direction facilitator. It’s onerous paintings, however scholars are ready to harvest the advantages and observe their wisdom to real-world issues after final touch.

We listen you could have a very good direction facilitator. How does he assist present scholars?

Sure! The direction facilitator, Allen Xu, collaborates with scholars in those Coursera categories—answering questions in dialogue boards, giving tips about beginning homework, and serving to reinforce the direction in response to pupil comments. He graduated from the MS-EE program and finished the Energetic Optical Gadgets Specialization, so he understands scholars’ wishes and has been impressed by way of the subject.

Thanks for taking the time to percentage your insights, and for construction such the most important program to make stronger newcomers keen to transport into this high-impact occupation box!


Professor Gopinath teaches 3 lessons on Coursera, which make up the Energetic Optical Gadgets Specialization:

  • Mild Emitting Diodes and Semiconductor Lasers: This direction explores semiconductor light-emitting diodes (LEDs) and lasers, in addition to the vital regulations for his or her research, making plans, design, and implementation.
  • Nanophotonics and Detectors: This direction examines nanophotonic light-emitting units and optical detectors, together with steel semiconductors, steel semiconductor insulators, and pn junctions. The curriculum additionally covers photoconductors, avalanche photodiodes, and photomultiplier tubes.
  • Shows: This direction dives into digital show units, together with liquid crystals, electroluminescent, plasma, natural light-emitting diodes, and electrowetting-based presentations. Scholars additionally know about quite a lot of design ideas, affordances and liabilities, and a number of programs in the true international {of professional} optics.

Scholars who take those lessons can observe their instructional credit score in opposition to the 100% on-line, versatile Grasp of Science in Electric Engineering (MS-EE) program—the one top-ranked on-line electric engineering graduate program and not using a utility and performance-based admission.*
