Abstract
We demonstrate a novel delay-line-free electro-optic sampling system by using a delay-time shifter which is modified from a microwave phase-locked loop. The ultrafast laser is inherently integrated with an electronic phase shifter which is modified from a microwave phase-locked loop. The voltage-controlled phase-shift as well as time- delay of the optical pulse is linear in the tuning of up to 1.9 period. The waveform sampling of the positive ECL signals generated from microwave frequency divider by using this system is demonstrated. The sampling results are compared with the same signals measured by conventional sampling scope. The distorted waveform of the ECL signal frequency-prescaled from microwave oscillator operated at high output level is observed. The divisor of the frequency presclar is found to vary from 2 to 5 at input power of less than -14DBm.
