Abstract

A photonic assembly, a laser setup having the photonic assembly and a method for performing frequency-modulated continuous-wave light detection and ranging using the laser setup are disclosed. The photonic assembly has an active photonic chip, a photonic modulator chip, and a tuning arrangement having a modulation element having a thickness of 10 micrometers or less. The active photonic chip and the photonic modulator chip are optically coupled such, that injection radiation at an optical feedback wavelength is generated, which defines at least one optical lasing wavelength at which the optical radiation is emitted by the active photonic chip. The modulation element is arranged such, that an actuation of the modulation element tunes the optical feedback wavelength via the Pockels effect, such, that a tuning of the optical feedback wavelength entails a tuning of the optical lasing wavelength.
