Symmetric coupler.

Parameters:

• gap – between straights in um.

• length – of coupling region in um.

• dy – port to port vertical spacing in um.

• dx – length of bend in x direction in um.

• cross_section – spec (CrossSection, string or dict).

• allow_min_radius_violation – if True does not check for min bend radius.
