<p>➀ A UWB, 0 to L band, polarization-insensitive (PI) 1×12 100GHz channel spacing arrayed waveguide grating (AWG) was designed and implemented a 3µm insulator on silicon (SOI) platform by VTT, with insertion losses ranging from -0.82 dB to -1.52 dB.</p><p>➁ A 3µm thick silicon waveguide has ultra-low propagation loss (0.1 dB/cm) and low birefringence over a wide wavelength range (1.2µm to 4µm).</p><p>➂ A 40-channel 100GHz spacing (de-mux/mux) multiplexer based on cascaded PEG was designed and manufactured on a 3µm SOI platform, with low crosstalk and low insertion loss.</p>
