| titleOfInvention | Continuous frequency modulation terahertz wave radar monolithic photonic integrated chip and radar system |
| abstract | The invention discloses a continuous frequency modulation terahertz wave radar monolithic photonic integrated chip and a radar system. The continuous frequency modulation terahertz wave radar monolithic photonic integrated chip includes: a first tunable laser, a second tunable laser, a coupler and a photodetector. The first tunable laser is used to generate a first optical signal with a first frequency; the second tunable laser is used to generate a second optical signal with a second frequency; the coupler is used to combine the first optical signal and the second optical signal multiplexing, and decomposing the combined optical signal into a first output signal and a second output signal output with equal power; the photodetector is used to convert the first output signal into a terahertz wave signal and radiate outward; wherein, the first tunable The laser, second tunable laser, coupler and photodetector are all formed on the same substrate. The invention can realize the integration and miniaturization of the terahertz wave radar, and improve the stability of the system. |
