“…The broadband optical frequency modulated linearization system which consists of one SSB modulator and two PMs is designed as shown in Fig 3. The system is divided into two parts in which a gated optical pulse is duplicated to many pulses with incremental (or decreasing) frequency shift, notated as f  , by passing the SSB modulator each time in the first part (see the blue frame in Fig 3) [13] . The frequency shift of the gated pulse for circulating one round in the loop, f  , is equal to the frequency of the applied signal on the SSB modulator, 1 m f .…”

Light detection and ranging (lidar) is used for various applications such as remote sensing, altimetry and imaging.Continuous wave frequency modulated (CWFM) lidars rely on linearly ramping the optical frequency of a laser and interfering the delayed echo signal with a reference signal to produce a beat frequency. The range resolution of lidar is determined by the swept frequency range of the linearly chirped continuous light waves in a frequency modulation system. For example, for 1mm range resolution, it needs the frequency sweep range of more than 150 GHz. In this paper a system which can generate a linearly chirped optical waveform within a super broad-wide band of 200 GHz, using cascaded phase modulators (PM) and single side band (SSB) modulator, is designed as a light source in a high resolution lidar system.
