At the end of the 1970s, it was confirmed that dielectric multilayers can sustain Bloch surface waves (BSWs). However, BSWs were not widely studied until more recently. Taking advantage of their high-quality factor, sensing applications have focused on BSW ...

We present a study of the dynamics of protein aggregation using a Bloch surface wave (BSW) label-free sensing scheme. In a previous work, we demonstrated the ability to detect the early dynamic events of fibrillogenesis of amyloid beta-peptides (A beta), l ...

Ultra-thin polymer optical waveguide couplers for integrated optics based on Bloch surface waves (BSWs) are presented. Desirable BSW guiding properties, such as low loss and long propagation distance, are observed. The waveguide thickness is on the order o ...

We investigate nondiffracting surface waves. On top of the Bloch surface wave platform, a 60-nm-thick TiO2 isosceles triangle serves as a 2D axicon. Scanning near-field microscopy measurements verify nondiffracting surface beam properties. ...
