Dr. Kashyap's research has led him into the field of photonic band-gap materials, also known as photonic crystals, in which
“artificial” structures are created to modify how light is entrapped. For example, in these perfect artificial
structures, light may not be allowed to escape, leading to a compact optical memory function, which is a highly desirable
function for a vast number of applications in medicine, communications and computer storage, and one which increases our
technological capability by orders of magnitude.
