Abstract: A distributed Bragg reflector (DBR) composed of Y2O3-doped HfO2 (YDH)/SiO2 layers with high reflectivity spectrum centered at a wavelength of ∼240 nm is fabricated using radio-frequency magnetron sputtering. Before the DBR deposition, optical properties for… read more here.

Abstract: A compact (4.49 μm × 4.54 μm) and ultra-broadband circular Bragg grating mirror with relaxed fabrication requirements is proposed and demonstrated based on the 220 nm silicon-on-insulator (SOI) platform. Based on FDTD-simulations, the proposed grating… read more here.

Abstract: We demonstrate a theoretical approach whereby light backscattering toward the incident beam can be suppressed entirely for a high-reflectivity, rough-surfaced multilayer mirror fabricated using oblique deposition, such that the interface relief is replicated at a… read more here.
