Analysis Tools

PICWave provides you with a large variety of analysis utilities.

  • Optical spectra (spectra of complex optical amplitude, including optical phase) - time averaged and
    time-evolving
Time evolving optical spectrum illustrating the effect of four-wave mixing in an SOA: although only three channels are injected (0nm, +1nm and 44nm), you can observe power in many other wavelengths generated by four-wave mixing

  • Intensity spectra (spectra of optical intensity) - time averaged and time-evolving
  • RIN Spectra

  • Longitudinal and lateral profiles (showing current spreading, carrier density, optical power, current distribution)
Longitudinal hole burning in a quarter-wavelength shifted DFB laser: (a) optical power along the z-axis (blue: total, green: forward, red: backward) and (b) carrier density along the z-axis at the centre of the laser
