An optical system and a method for non-mechanically (i.e., without physical movement) scanning a laser using a lens, a steering optical element, and an array of transmission paths configured to simultaneously emit a same wavelength of electromagnetic radiation.

Multi-beam laser scanner with programmable field of view

A LiDAR system including a laser amplification system is disclosed. The laser amplification system includes a laser source and an optical amplifier. The laser source has a laser cavity and is configured to output electromagnetic radiation. The optical amplifier includes quantum dots and is positioned outside the laser cavity to receive the electromagnetic radiation output from the laser source. The optical amplifier amplifies the received electromagnetic radiation using the quantum dots and outputs the amplified electromagnetic radiation.

Chip-scale coherent lidar utilizing quantum dots

An optical system and a method for non-mechanically (i.e., without physical movement) scanning a laser using a lens, a steering optical element, and transmission and receive paths having a non-zero spatial offset. Also, an optical system and a method for non-linearly and non-mechanically scanning a laser using a lens and a steering optical element, such that detection points resulting from the scanned laser are non-linearly mapped into space.

Multi-beam, wavelength-tuned laser scanning

An optical system is provided including a photonic integrated circuit and an optical lens system. The photonic integrated circuit includes an emission interface surface and a spatial array of apertures. The spatial array of apertures has a high numerical aperture (NA) of greater than 0.2 and includes a plurality of apertures spatially distributed across the interface surface. The optical lens system interfaces the photonic integrated circuit with free space by: receiving emitted light from the spatial array of apertures and altering a trajectory of the emitted light into the free space and receiving returning light from the free space and altering a trajectory of the returning light, such that the returning light is received by the spatial array of apertures.

Simplified lens for photonic integrated circuits

A device and method for performing reflectivity measurements at a distance by receiving two or more reflected signals (using two or more different wavelength sweeps) and calculating ratios of the two (or more) received reflected signals, for the purpose of determining the composition of a material or surface at a distance.

Method of spectroscopically characterizing a surface

An adaptive lag angle compensation scheme for coherent high-speed scanning LiDAR that accommodates diffraction-limited LiDAR beams and also accommodates mixing of return signals with the corresponding local oscillator signals.

Coherent high speed scanning lidar

A LiDAR system comprising a laser source configured to output electromagnetic radiation based on an input signal and circuitry configured to supply the input signal to the laser source to control electromagnetic radiation output by the laser source, such that the laser source outputs a waveform including a plurality of output states. The laser source outputs electromagnetic radiation having a particular wavelength during the output states. Each of the plurality of output states is separated in time from neighboring output states of the plurality of output states by a time span. The particular wavelength of the electromagnetic radiation for a first output state of the plurality of output states is different from the particular wavelength of electromagnetic radiation for a second output state of the plurality of output states.

Digital coherent LiDAR with arbitrary waveforms

A method for controlling an electromagnetic radiation source to produce single mode operation having an optimized side-mode suppression ratio over a set of wavelengths within a prescribed temporal profile. The electromagnetic radiation source is configured to output electromagnetic radiation at a given wavelength based upon parameters. The method includes determining a set of parameter combinations that satisfy a condition for a desired set of wavelengths and a minimum side mode suppression ratio over the range of wavelengths. The set of parameter combinations define sub-paths for nearly arbitrary transitions from one wavelength to another wavelength. Combinations of select sub-paths provide a multivariate path for transitioning over the range of wavelengths. The method also includes controlling the semiconductor laser to emit electromagnetic radiation over the range of wavelengths by traversing the multivariate path in a desired manner.
