Abstract
Disclosed herein is a pulse repetition rate multiplier including a photonic integrated circuit (PIC) including cascading Mach-Zehnder interferometers (MZIs). An input may be connected to one end of the PIC and an output may be connected to the other end of the PIC such that a signal from the input runs through the cascading MZIs and out the output. The input may be configured to receive an input pulsed signal and the output may be configured to output a repetition rate multiplied signal. Advantageously, using a PIC as opposed to an optical fiber-based pulse rate multiplier allows for accurate fabrication of a pulse repetition rate multiplier configured to accept higher frequency pulsed signals.
