Webfrequency-fixed optical carrier with a frequency-chirped optical carrier. But the beating of two phase uncorrelated lasers induces high phase noise and nonlinearity chirp due to the phase and
First, an experiment is performed to demonstrate the operation of the hybrid FDML laser with the use of the silicon photonic integrated MDR chip. Since the length of the laser cavity is around 9 km, a round-trip time is calculated to be about 44.4 µs. In the experiment, a driving signal with a repetition time of 44.7 µs … See more A hybrid FDML laser is realized based on a fiber ring cavity in which a tunable optical filter is incorporated to perform Fourier-domain … See more Then, the generated frequency-chirped optical pulse is combined with a CW optical carrier from an LD and beat at a high-speed PD. At the output of the PD, an LCMW is generated. … See more WebThe term “chirped” came from radar technology where it was used earlier for similar pulse manipulation. A chirp is called positive if lower frequency light travels ahead of higher frequency light and negative if opposite holds.
WebTechniques for adaptive scanning with a laser scanner include obtaining range measurements at a coarse angular resolution and determining a range gate subset and a characteristic range.
