Grating couplers enable position-friendly interfacing of silicon chips by optical fibers. The conventional coupler designs call upon comparatively complex architectures to afford efficient light coupling to sub-micron silicon-on-insulator (SOI) waveguides. Conversely, the blazing effect in double-etched gratings provides high coupling efficiency with… (More)
Experimental demonstration of an O-band four channel CWDM silicon nitride AWG is reported. Specificity of low order array has been explored through multiple devices among which insertion loss below 2.3dB, crosstalk level as high as 37dB and polarization insensitive spectral response flattening is obtained.
