The patent application (Publication Number: US20240030674A1) describes a system comprising a wavelength-tunable light source and a controller that controls the attenuation and wavelength change of the light emitted by the source. The system allows for the emission of pulses of light at different wavelengths, enabling applications such as distance measurement based on the time of arrival of the emitted pulses.

The system includes components such as a seed laser diode, an optical amplifier, and a controller that work together to produce light at specific wavelengths. By applying different bias states to the optical amplifier and adjusting electrical currents to the seed laser diode, the system can generate light pulses at desired wavelengths. Additionally, a monitoring module with an etalon and detector is included to monitor the current wavelength of the produced light. These features enable precise control over the emitted light pulses, making the system suitable for applications requiring accurate distance measurements based on light propagation times. Overall, the system's design and functionality offer a versatile solution for various optical applications that rely on controlled light emission and wavelength tuning.
