Abstract

We present a resonance waveguide grating with relatively wide bandwidth in the visible region of the spectrum compared to typical resonance structures. The reflective properties of the grating are based on amorphous atomic layer deposited titanium dioxide which has rather high refractive index at the visible wavelengths. The resonance grating provides approximately 20–30 nm bandwidth with over 90% reflectance at the visible wavelengths. The measured reflectances of the fabricated elements show also very good agreement with the theoretical predictions. These kind of reflectors may be useful in applications that make use of LED sources.

Fig. 4

Reflectance of the RWG grating for the incident angle of 20 degrees in TE- and TM-polarizations. The period of the grating d = 378 nm, the height hg = 106 nm, the fill-factor f = 0.26, and the thickness of the TiO2 coating is hc = 56 nm. TE exp and TM exp denote the measured reflectance curves and TE theory and TM theory are the corresponding calculated reflectances.

Reflectance of the RWG grating for the incident angle of zero degrees in TE- and TM-polarizations. The period of the grating d = 390 nm, the height hg = 120 nm, the fill-factor f = 0.25, and the thickness of the TiO2 coating is hc = 68 nm. TE exp and TM exp denote the measured reflectance curves and TE theory and TM theory are the corresponding calculated reflectances.

Fig. 6

Theoretical reflectance of the RWG grating determined from the transmittance using the relation R = 1 − T. The solid lines represents the case where we take into account only the zeroth transmitted order in the substrate. The dashed lines represents the case where we take into account all the transmitted orders in the substrate. Furthermore, in both cases the grating profile is rounded to match the fabricated profile shown in Fig. 3. Because the cut-off wavelength of the grating is approximately at 574 nm, the solid and dashed lines overlap above this wavelength.
