The new grating design enables weak grating coupling strength and adjustable effective index without compromise, thus is relatively insensitive to the grating width variation. The Bragg wavelength of cladding-modulated grating could be tuned by changing not only the grating period but also the core waveguide width without obviously affecting the optical reflection bandwidth.
