Figure 4 Typical performance of thermal phase shifters for (a) strip waveguide configuration, (b) rib waveguide configuration and (c) switching speed for both waveguide configurations.

Figure 6 Measured DC performance of a 1.8 mm long Si depletion modulator. (a) Phase shift and (b) modulator efficiency.

Figure 10 Insertion  loss  in  dB  for  the  apodized  focusing  grating  couplers:  (a)  220  nm  platform  optimized for the H-Fb scheme, (b) 340 nm platform optimized for the H-Fb scheme, and (c) 340 nm platform optimized for the V-Fb scheme.

Figure 12 Side  views  (a,b) and top view (c) of the 2D emitted power distribution from the grating structures. Apodized  gratings  (a)  allow  for  light  to  travel  further  into  the  device  than  the  non-apodized gratings (b).  Top  view  is  the  2D power distribution in the (x-y) plane taken at a height, z 310   μm above the chip, showing a focus point 10 μm in diameter.

Figure 14 Si nitride device library: (a) grating coupler; (b) multimode interferometer; (c) directional coupler, (d) Mach–Zehnder interferometer; (e) angled-multimode interferometer (reprinted from [95], The  Optical  Society,  2017);  (f)  (de)multiplexer  response  in  the  O-band  and  (g)  (de)multiplexer  response in the C-band.
