摘      要：Swept laser interferometry is an extremely powerful solution embedded in several recent technologies such as absolute distance measurement,light detection and ranging(LiDAR),optical frequency domain reflectometry,optical coherence tomography,microresonator characterization,and gas *** in the optical frequency sweeping of tunable lasers is a fatal drawback in gaining the expected outcome from these ***,we introduce an on-chip,millimeter-scale,7 m spiral resonator that is made of ultralow-loss Si_(3)N_(4)to act as a frequency ruler for correction of the tunable lasers sweeping *** sharp 2 MHz frequency lines of the 8.5×10^(7)high-quality factor resonator and the narrow-spaced 25.566 MHz frequency ticks of the 7 m spiral allow unprecedented precision for an on-chip solution to correct the laser sweeping *** measurements of the ruler’s frequency spacing,linewidth,and temperature and wavelength sensitivities of the frequency ticks are performed here to demonstrate the quality of the frequency *** addition,the spiral resonator is implemented in an frequency-modulated continuous-wave LiDAR experiment to demonstrate a potential application of the proposed on-chip frequency ruler.
