(PhysOrg.com) -- In a new study, scientists have shown that simply tailoring the nanoscale geometrical parameters of dielectric structures can result in an increase in the light intensity to unprecedented levels. Theoretically, they calculate that the light intensity could be increased to up to 100,000 times that of the incident intensity over large volumes. This large light enhancement could lead to new developments in all-optical switching and biosensing applications.
