The maximum scanning speed, time, responsivity, and resolution of the optoelectronic delay line are 100 points/s, 3.6 ns (1.8 periods), 0.54 ns/V, and 0.2 ps, respectively. The waveform-sampling of a sinusoidal signal at 500 MHz and an electrical pulse with 91.5-ps full-width at half-maximum generated from a microwave oscillator and comb generator, respectively, are reported with measurement error of less than 5%.Delay-time controller; Electro-optic sampling; Optoelectronic; Phase-shifter; Pulsed laser[SDGs]SDG7Delay control systems; Laser pulses; Microwave oscillators; Phase shifters; Sampling; Semiconductor lasers; Threshold voltage; Tuning; Delay time controller; Delay time pulsed laser diode; Electrooptic sampling; Optoelectronic phased locked phase shifter; Optomechanic delay line; Electrooptical devicesjournal article10.1143/jjap.41.60032-s2.0-0036819289
