Layout

All UBC ubcpdk.components cells are conveniently combined into the ubcpdk.components module.

import gdsfactory as gf

import ubcpdk.components as uc

Fixed Component cells

Most ubcpdk components are imported from GDS files as fixed cells.

c = uc.ebeam_crossing4()
c.plot()

c = uc.ebeam_swg_edgecoupler()
c.plot()

c = uc.ebeam_bdc_te1550()
c.plot()

c = uc.ebeam_adiabatic_te1550()
c.plot()

c = uc.ebeam_y_adiabatic()
c.plot()

c = uc.ebeam_y_1550()
c.plot()

Parametric Component PCells

You can also define cells adapted from gdsfactory generic pdk.

c = uc.straight(length=2)
c.plot()

c = uc.bend(radius=5)
c.plot()

c = uc.ring_with_crossing()
c.plot()

c = uc.dbr()
c.plot()

c = uc.spiral()
c.plot()

c = uc.mzi_heater()
c.plot()

c = uc.ring_single_heater()
c.plot()

Components with grating couplers

To test your devices you can add grating couplers. Both for single fibers and for fiber arrays.

splitter = uc.ebeam_y_1550()
mzi = gf.components.mzi(splitter=splitter)
mzi.plot()

component_fiber_array = uc.add_fiber_array(component=mzi, fanout_length=5)
component_fiber_array.plot()

c = uc.ring_single_heater()
c = uc.add_fiber_array_pads_rf(c)
c.plot()

c = uc.mzi_heater()
c = uc.add_fiber_array_pads_rf(c)
c.plot()

3D rendering

scene = c.to_3d()
scene.show()
