Wavelength selective coupler with vertical gratings on silicon chip

Ikeda, K.; Nezhad, M.; Fainman, Y.

Abstract

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 designed wavelength selective coupler and demonstrate the expected operation. The available wavelength-division-multiplexing bandwidth of this device is not limited by free spectral range as in ring resonators. We also propose some applications of the wavelength selective coupler.
