our products

DeepLight’s products are ultra-narrow linewidth laser, with high power, unprecedented tuning bandwidth in compact form factor, with integrated triangular waveform generator for direct use in FMCW coherent laser ranging. The lasers are available for several wavelengths from the visible to the IR. Our technology is based on photonic integrated circuits compatible with wafer-scale manufacturing. The laser combines the noise of a fiber laser, frequency agility of a diode laser with unprecedentedly fast and linear tuning.


  • Unprecedented flat tuning bandwidth of 10 MHz
  • Continuous laser frequency tuning of 10 GHz
  • High power >17 dBm (50 mW) output power at 1550 nm
  • Highly linear tuning, no hysteresis
  • Linearization free FCMW signal
  • Ultra-low frequency noise (< 100 Hz short term linewidth) comparable with bulk fiber lasers
  • Coherence length >500 km
  • Photonic integrated circuit-based technology
  • Compact OEM packaging
  • In-package integrated triangular FMCW signal generator (nonlinearity <0.5%)

Our lasers are packaged in a 14-pin, OC-48 compatible hermetic butterfly packaging designed to be immune to mode or optical frequency hopping. Wide operating temperature range is achieved by using built-in industry-proven TECs and thermistors. The device is DC coupled, with built-in FMCW laser scanning electronics.

An integrated photonics and electronics architecture is crucial for LiDAR applications with stringent requirements that provide long-term stability free of drifts and changes in response function. It allows using of more complicated modulation signals.
