Focused apodized forked grating coupler

WebUsing this method, a fully etched apodized grating coupler is designed and demonstrated on the SOI platform using PhCs to engineer the refractive index of each scattering slot. An ultralow coupling loss of −1.74 dB (67% coupling efficiency) with a 3 dB bandwidth of 60 nm is demon- strated. Webwith the Gaussian fiber mode. However, an apodized grating requires feature sizes which are beyond the limit of current 193nm DUV lithography. For case 2(c), no waveguide etch e is required. This kind of grating coupler has been theo-retically reported in [13], where a transferred silicon nanomenbrane is proposed in order to fabricate the grating.
