We propose a generic method for efficient maneuvering of surface plasmon polariton (SPP) modes along irregularly shaped metal–dielectric interfaces using strategically placed complementary medium inserts. The main attractiveness of our method is it enables us to steer SPPs through curved interfaces in a nearly lossless way while preserving the mode pattern. The complementary medium inserts can be...
Total internal reflection (TIR) is a ubiquitous phenomenon used in photonic devices ranging from waveguides and resonators to lasers and optical sensors. Controlling this phenomenon and light confinement are keys to the future integration of nanoelectronics and nanophotonics on the same silicon platform. We introduced the concept of relaxed TIR, in 2014, to control evanescent waves generated during...
