Photopolymer-based Surface-normal Input/Output Volume Holographic Grating Coupler for 1550-nm Optical Wavelength

Year: 2012

Type: article

Abstract: A surface-normal input/output volume holographic grating coupler (VHGC) operating at 1550nm wavelength region by using a $10{\mu}m$ -thick DuPont photopolymer film is designed and fabricated. The angular and wavelength responses of the input/output VHGC are investigated in order to validate applicability of this device in integrated optics and optical communications. The effect of incident-beam position on the output reflectance to determine optimum condition for input coupling is also presented. The fabricated input/output VHGC exhibited an angular selectivity of ${\sim}0.027^{\circ}$ , a wavelength selectivity of ~0.8 nm, and an output peak reflectance of 34.13%.
