Today's standard fabrication processes are just capable of manufacturing slab of photonic and phononic crystals, so an efficient method for analysis of these crystals is indispensable. Plane wave expansion (PWE) as a widely used method in studying photonic ...
Large-scale (50x50 and 64x64) integrated photonic switches have been realized by combining silicon photonics with efficient micro-electro-mechanical-system (MEMS) switching mechanisms. Low on-chip loss (0.058dB/port) and sub-microsecond switching time have ...
Fast optical circuit switches (OCSs) with high port count offer reconfigurable bandwidth in optical networks and have the potential to significantly increase the performance and efficiency of modern datacenters. In this paper, we report on a new type of in ...

Integrated microresonators are essential building blocks of linear and nonlinear photonic devices. Here we show that the performance of high-Q silicon nitride microresonators for nonlinear photonics strongly depends on the ideality of their coupler design. ...

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 ...
