Photonic microwave filter employing multimode optical sources and wideband chirped fibre gratings

A compact photonic microwave filter employing multimode lasers and wideband chirped fibre gratings is proposed. Experimental results are provided using a Fabry-Perot laser as a multimode optical source and a 4 nm chirped fibre grating with a group delay slope of nearly 400 ps/nm and single-mode optical fibre as the wideband dispersive media.
