An integrated-optic RF spectrum analyzer (IOSA) using a focusing grating coupler (FGC) is proposed and demonstrated. The use of the FGC as a Fourier transform element allows photodetector coupling with a spot size to pixel size matching and relaxes fabrication accuracy requirements; thus the IOSA has potential advantages of a high resolution, wide bandwidthand high dynamic range. The design consideration of the FGC shows that an IOSA of a 1.5 MHz resolution and 1-GHz bandwidth is feasible. A fully-integrated IOSA was fabricated by integrating an acoustooptic Bragg cell, a FGC and a proton-exchanged Fresnel lens in a Ti: LiNbO<SUB>3</SUB>waveguide, followed by coupling a laser diode and a CCD linear image sensor. The IOSA operation of a 6-MHz resolution was experimentally obtained.
