gdsfactory.path.euler

Returns an euler bend that adiabatically transitions from straight to curved.

radius is the minimum radius of curvature of the bend. However, if use_eff is set to True, radius corresponds to the effective radius of curvature (making the curve a drop-in replacement for an arc). If p < 1.0, will create a “partial euler” curve as described in Vogelbacher et. al. Vogelbacher et al. (2019)

Parameters

• radius – minimum radius of curvature.

• angle – total angle of the curve.

• p – Proportion of the curve that is an Euler curve.

• use_eff – If False: radius is the minimum radius of curvature of the bend. If True: The curve will be scaled such that the endpoints match an arc with parameters radius and angle.

• npoints – Number of points used per 360 degrees.
