Paper Abstract

By suitably modulating a single multielectrode semiconductor laser and processing the optical output, a wideband frequency-swept signal from near-dc to millimeter frequencies can be generated. Initial results reveal that a usable sweep range from 60 MHz to 22 GHz (receiver-bandwidth-limited) can be achieved with low-residual amplitude modulation, with bandwidths of greater than 125 GHz being possible. Generated frequency resolution is limited in laser frequency stability and linewidth.
