OE4000 Optical Phase Noise/Linewidth/RIN Analyzer

The HI-Q® OE4000 is a homodyne optical discriminator with a modular design characterized by very low noise floor.  This analyzer measures spectral density of the phase/frequency noise of optical sources, laser linewidth and offers the option for RIN (intensity noise) measurement. The proprietary measurement technique employed in the OE4000 does not require a second low noise source for reference and the analyzer system is fully automated.  The OE4000 has many different configuration options of wavelength bands, noise floors and various options.  Multiple bands and combined bands can be chosen, there are RIN measurement options that extend out to 40GHz and all configurations are upgrade-compatible.  Topics focus on:

  • OE4000 Homodyne Phase Noise/Linewidth/RIN Analyzer System
  • Benefits of measuring spectral density of phase/frequency noise vs. basic linewidth measurement
  • OE4000 GUI and user-friendly features and benefits
  • OE4000 configuration options
