What is "Photonics"?

Photonics vs. Optics

Optics and photonics are often used interchangeably, although their meaning can vary depending on the context. In fact, an ongoing debate among experts has yet to find a conclusion on what the exact differences are [1]. Here is our take on it: "optics" often refers to the classical concept of light rays, the study of vision, and the transmission, reflection, and absorption of light in different media [2]. In contrast, "photonics" emphasizes the quantum mechanic dual character of light, in particular the "quanta" of light (the photons!) [3]; moreover, it also often refers to the technologies and the industry that involve optics and optical instruments [2].

This, of course, is only a brief summary of online sources, and one could discuss in length more details. If you want to share your thoughts, send us an email!

Welcome to Harvard SEAS Photonics Club!

Harvard SEAS Photonics Club is a student-run organization whose mission is to educate students on research related to optics and photonics. We hope to provide Harvard students who are new to the field, graduate and undergraduate alike, with opportunities to expand their interest and knowledge in research being done in the growing fields of optics and photonics both within and outside of Harvard University.

Our group is new and still growing. We are very open to working on and developing new programs, whether academic, social, outreach oriented, or anything else you can think of. If you have any suggestions or are just interested in taking part, please e-mail us at photonics@seas.harvard.edu! You can also join the mailing list (via google group) to stay in touch!
