Abstract arrayed waveguide grating.

A demultiplexer with one common port and num_channels outputs, built on MuxDemuxModel.

Args

• num_channels: Number of output channels.
• channel_spacing: Spacing between channel centres.
• center_wavelength: Centre of the channel comb.
• bandwidth: 3 dB bandwidth per channel.
• free_spectral_range: Response period, in μm. Zero disables aliasing.
• periodic_orders: How many grating orders each side of the design one are represented.
• insertion_loss: Loss of the centre channel.
• nonuniformity: Edge-to-centre transmission drop.
• crosstalk: Crosstalk floor.
• order: Butterworth order. 1 to 2 for a Gaussian-like passband, higher for flat-top.

Returns

Component with num_channels + 1 optical ports. The first is the common port.
