FiberCouplerGrating

class picazzo3.fibcoup.base.FiberCouplerGrating(*args, **kwargs)

Base class for fiber couplers which combine a grating on top of a socket.

The socket is the piece of waveguide, taper or slab on which the grating rests. The grating couples light between the plane (the socket) and the out-of-plane direction, to a fiber, lens or free space.

This cell should be used such that the inclination and angle of the port match the direction of peak transmission at the center wavelength specified in the circuitmodel, when light is incident from the vertical (through vertical_in) and couples to the out port
