Optical signal data format (1)
Signal type Data elements Comments
Sampled InputPort1.Sampled.Signal Represents the complex envelope of the optical signal (real/imag) – 1xn complex double
If there are two polarization states, two rows will be created (2xn complex double)
InputPort1.Sampled.Time
Inputport1.Sampled.Frequency
The time/frequency sampling points for the sampled optical signal (s or Hz)
• If the parameter Sampled signal domain = “Time”, use InputPort1.Sampled.Time
• If the parameter Sampled signal domain = “Frequency”, use
InputPort1.Sampled.Frequency
InputPort1.Sampled.CentralFrequency The center frequency (Hz) of the optical signal
Sampled
(Channels)
InputPort1.Channels List of wavelength channels entering specified port
• To access data for a sampled signal (Channel A), use InputPort1.Sampled(A).Signal,
etc.
• To access data for a parameterized signal (Channel A), use
InputPort1.Parameterized.Power(A), etc.
Sampled
(Spatial)
InputPort1.Sampled.Spatial.ModeX.Amplitude Real or complex amplitude of spatial mode(s) – nxn array
Note 1: To access Y polarization data, use ModeY in lieu of ModeX
Note 2: If more then one mode is present, separate sampled signals will be created for
each mode and can be accessed as follows (for Mode A):
InputPort1.Sampled(A).Spatial.ModeX.Amplitude
InputPort1.Sampled.Spatial.ModeX.Properties String value (describes mode type and index)
InputPort1.Sampled.Spatial.ModeX.DeltaSpaceX
InputPort1.Sampled.Spatial.ModeX.DeltaFrequencyX
X-polarization: Discretization in space (m) or discretization in frequency (1/m)
InputPort1.Sampled.Spatial.ModeX.DeltaSpaceY
InputPort1.Sampled.Spatial.ModeX.DeltaFrequencyY
Y-polarization: Discretization in space (m) or discretization in frequency (1/m)
Parameterized InputPort1.Parameterized.Power Average power of parameterized optical signal (W)
InputPort1.Parameterized.Frequency Central frequency of parameterized optical signal
InputPort1.Parameterized.SplittingRatio Polarization splitting ratio of parameterized optical signal
InputPort1.Parameterized.Phase Phase of parameterized optical signal

Sampled InputPort1.Sampled.Signal Represents the electrical signal sampled waveform (real/imag) – 1xn complex double
InputPort1.Sampled.Time
Inputport1.Sampled.Frequency
The time/frequency sampling points for the sampled electrical signal (s or Hz)
