Models suspended Si¶

SAX models registered in PDK.models, evaluated at their default parameters. Plots show the transmission between optical ports over +-3 % of each model's centre wavelength.

bend_circular¶

Returns the S-matrix of a circular bend (straight-waveguide propagation).

Parameter	Default
`wl`	`3.8`
`radius`	`None`
`angle`	`90.0`
`loss`	`5.0`
`cross_section`	`'xs_sus'`

bend_euler¶

Returns the S-matrix of an euler bend (straight-waveguide propagation).

Parameter	Default
`wl`	`3.8`
`radius`	`None`
`angle`	`90.0`
`p`	`0.5`
`loss`	`5.0`
`cross_section`	`'xs_sus'`

bend_euler

bend_s¶

Returns the S-matrix of the cosine S-bend (straight-waveguide propagation).

Parameter	Default
`wl`	`3.8`
`size`	`(40.0, 8.0)`
`loss`	`5.0`
`cross_section`	`'xs_sus'`

grating_coupler_rectangular¶

Returns the S-matrix of the foundry grating coupler (placeholder).

Parameter	Default
`wl`	`3.8`
`loss`	`6.0`
`bandwidth`	`0.15`
`cross_section`	`'xs_sus'`

grating_coupler_rectangular

straight¶

Returns the S-matrix of a straight suspended waveguide.

Parameter	Default
`wl`	`3.8`
`length`	`10.0`
`loss`	`5.0`
`cross_section`	`'xs_sus'`

straight

taper¶

Returns the S-matrix of a taper (phase of the 1.5um core, no mode mismatch).

Parameter	Default
`wl`	`3.8`
`length`	`10.0`
`loss`	`5.0`
`cross_section`	`'xs_sus'`
