2021 Explorer

Physics Unlimited's 2021 Explorer Competition consists of an open-ended assignment to learn the foundational principles and apply them to effectively design a quantum cascade laser. Students will be able to work on this task at any time through the extended submission deadline of March 21, 11:59 pm ET.


Registration will remain open for any new teams to enter or existing teams to edit their details. Please follow this link to complete the registration form for your team (only one person/team needs to do so) anytime before the extended submission deadline of your work on March 21st.
We hope this exercise will serve as an enriching experience for everyone, and we look forward to seeing all participants develop their critical thinking skills in the process!
