À propos du Spécialisation Active Optical Devices

The courses in this specialization can also be taken for academic credit as ECEA 5605-5607, part of CU Boulder’s Master of Science in Electrical Engineering degree. Enroll here. This Active Optical Devices specialization is designed to help you gain complete understanding of active optical devices by clearly defining and interconnecting the fundamental physical mechanisms, device design principles, and device performance. You will study and gain active experience with light emitting semiconductor devices like light emitting diodes and lasers, nanophotonics, optical detectors, and displays. Specialization Learning Outcomes: *Analyze and design semiconductor light sources, and surrounding optical systems *Analyze and design detection systems for LIDAR, microscopy and cameras *Analyze and design systems for optical device systems that can adapt to the environment at hand. *Use lasers and optical electronics in electronic systems through an understanding of the interaction of light and atoms, laser rate equations and noise in photo-detection....

Foire Aux Questions

  • Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:

    • The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.

    • The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

  • When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.

  • If you subscribed, you get a 7-day free trial during which you can cancel at no penalty. After that, we don’t give refunds, but you can cancel your subscription at any time. See our full refund policy.

  • Yes, Coursera provides financial aid to learners who cannot afford the fee. Apply for it by clicking on the Financial Aid link beneath the "Enroll" button on the left. You'll be prompted to complete an application and will be notified if you are approved. You'll need to complete this step for each course in the Specialization, including the Capstone Project.
