Waveguide template objects are used to define a standard set of parameters (width, cladding, layers, etc.) that is passed to waveguide routes and PICwriter components.
.. automodule:: picwriter.components :members: WaveguideTemplate
Example usage:
To generate a strip waveguide template with 1.0um width and 25.0um bending radius:
wgt= WaveguideTemplate(wg_type='strip', wg_width=1.0, bend_radius=25)
To generate a slot waveguide with 1.0um width, 25.0um bending radius, and a 0.3um slot in the center:
wgt = WaveguideTemplate(wg_type='slot', wg_width=1.0, bend_radius=25.0, slot=0.3)
To generate a sub-wavelength grating waveguide with 1.0um width, 25.0um bending radius, 50% duty-cycle, and a 1um period:
wgt= WaveguideTemplate(wg_type='swg', wg_width=1.0, bend_radius=25, duty_cycle=0.50, period=1.0)
Waveguide objects are fully defined by a WaveguideTemplate object as well as a list of (x,y) points that determine where the waveguide is routed.
.. automodule:: picwriter.components :members: Waveguide
Example usage to generate a waveguide with waypoints:
top = gdspy.Cell('top')
wgt= WaveguideTemplate(wg_type='strip', wg_width=1.0, bend_radius=25)
waypoints = [(0, 0), (200, 0), (250, 100), (400, 100)]
wg = Waveguide(waypoints, wgt)
tk.add(top, wg)
