We introduce exotic optical elements for 2D surface wave systems hosting Bloch surface waves (BSWs). First, we will study a 2D non-diffracting beam, second, a 2D array of the optical bottle beam via the Talbot effect and third, tight light confinement like a photonic nanojet. Investigations are carried out using a well-established BSW platform.
