| Abstract: | A novel scheme is proposed to transform an ultra-short optical pulse to a millimeter-wave frequencymodulated 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 reflectivities,and different cascading numbers.It is shown that the cascading does not introduce much effect on the extinction ratio.Two designs by using Gires-T... |
