get_angles_out

awg_designer.all.get_angles_out(delay_length, frequencies, grating_period, n_eff_wg, n_eff_slab)

Get the angles for the output grating, so that the output channels are positioned at the specified frequencies.

Parameters

delay_length: float

Delay length.

frequencies: (list of floats)

List of center frequencies for each channel.

grating_period: float

Period of the AWG grating apertures.

n_eff_wg: (list of floats)

Effective index of the waveguides at each of these channel wavelengths.

n_eff_slab: (list of floats)

Effective index of the slab at each of the channel wavelengths.

Returns

List of output angles at which the output apertures must be placed to get center frequencies as specified.
