Magnetic spin–orbit interaction of light

Hans Peter Herzig, Myun Sik Kim, Maria-Pilar Bernal, Huihui Lü

We study the directional excitation of optical surface waves controlled by the magnetic field of light. We theoretically predict that a spinning magnetic dipole develops a tunable unidirectional coupling of light to transverse electric (TE) polarized Bloch ...

Magnetic Spin-Orbit Interaction of Light Steers Bloch Surface Waves

Hans Peter Herzig, Myun Sik Kim, Maria-Pilar Bernal, Huihui Lü

We show the directional excitation of Bloch surface waves controlled by the magnetic field of light. The phenomenon in play is the first magnetic spin-orbit interaction of light. It opens new degrees of freedom in the manipulation of light and offers appea ...

Experimental evidence of Bloch surface waves on photonic crystals with thin-film LiNbO3 as a top layer

Hans Peter Herzig, Myun Sik Kim, Maria-Pilar Bernal

Strong nonlinear, electro-optical, and thermo-optical properties of lithium niobate (LN) have gained much attention. However, the implementation of LiNbO3 in real devices is not a trivial task due to difficulties in manufacturing and handling thin-film LN. ...

Polarization controlled directional propagation of Bloch Surface Wave

Hans Peter Herzig, Myun Sik Kim, Maria-Pilar Bernal

Bloch surface waves (BSWs) are recently developing alternative to surface plasmon polaritons (SPPs). Due to dramatically enhanced propagation distance and strong field confinement these surface states can be successfully used in on-chip all-optical integra ...

Polarization controlled directional excitation of Bloch surface waves

Hans Peter Herzig, Myun Sik Kim, Maria-Pilar Bernal

Bloch surface waves (BSWs) are electromagnetic surface waves which can be excited at the interface between periodic dielectric multilayer and a surrounding medium. In comparison with surface plasmon polaritons these surface states perform high quality fact ...

Demonstration of Bloch Surface Waves in crystals with LiNbO3 thin films

Hans Peter Herzig, Myun Sik Kim, Maria-Pilar Bernal

A novel one dimensional photonic crystal (1DPHC) sustaining Bloch surface waves (BSWs) with a single crystal thin film lithium niobate (TFLN) as a part of a multilayer is theoretically and experimentally investigated. Properties of the dielectric multilaye ...

Strong improvement in the photonic stop-band edge sharpness of a lithium niobate photonic crystal slab

Paul Muralt, Scott Harada, Maria-Pilar Bernal

We report on a photonic crystal (PhC) etched into a 380 nm thick lithium niobate (LN) thin film deposited on a MgO substrate by pulsed laser deposition. The transmission properties of this device were assessed by optical near-field measurements and compare ...
