I am curious about the differences between optics in the fields of (Bio)engineering and physics. Mainly, I'm interested in finding out how the research differs between the two fields and which would be the best for an undergraduate who is interested in graduate school. From what I understand, there can be quite a bit of overlap, but which would prepare me better for graduate school in say biomedical optics? I am assuming that a BS in bioengineering would better prepare me for more applied research that involves development of new biomedical instruments and imaging/optics techniques. Whereas physics would give me a better knowledge base of the theory behind optics as apposed to the instrumentation and research would be more concerned with how molecules/materials interact with light, etc. Can someone correct me and/or add to this? I am only a freshman (in bioengineering) but at this point I am more interested in possibly pursuing research more on the "physics side of things". Will a bioengineering BS with a minor in math and physics prepare me for graduate study in a physics program in optics or at least an engineering program that is more physics based in their research? Would a physics BS allow me to pursue graduate school in bioengineering or vise versa? I would like to be as flexible as possible after undergrad. Appreciate your help!
