Abstract
A novel scheme is proposed to transform an ultra-short optical pulse to a millimeter-wave frequency-modulated pulse by using the cascaded all-pass cavities (APCs). The envelope waveform of the generated pulse train is calculated, showing effective improvement by APC cascading. The extinction ratio is analyzed with different input pulses, different cavity re°ectivities, and di?erent cascading numbers. It is shown that the cascading does not introduce much effect on the extinction ratio. Two designs by using Gires-Tournois cavity and waveguide ring resonators are proposed to realize the cascaded APC.
