Abstract: A silicon-based on-chip ultra-sharp multimode waveguide bend (MWB) is proposed to work for dual polarizations by introducing modified Euler-curves and shallowly-etched non-uniform subwavelength-gratings (SWGs). For the designed 90° MWB with a core width of 1.01 μm… read more here.

Abstract: In this paper, we report the generation of an ultra-sharp asymmetric resonance spectrum through Fano-like interference. This generation is accomplished by weakly coupling a high-quality factor (Q factor) Fabry-Pérot (FP) cavity and a low-Q factor… read more here.
