Wavelength selective coupler with vertical gratings on silicon chip

Kazuhiro Ikeda, Maziar Nezhad, and Yeshaiahu Fainman
We propose a wavelength selective coupler using vertical grating structure on silicon chip and discuss the operation principle and the analytic design procedure. The transmission spectra expected by the procedure agree with finite difference time domain simulation results. We then fabricate the desi ... [Appl. Phys.
