A fabrication process for PFCB waveguide air-trench bends and splitters with scanning electron microscope (SEM)-based electron beam lithography (EBL) with alignment accuracy better than 40 nm has been developed. High efficiency air-trench bends (97.2% for TE polarization and 96.2% for TM polarization) have been demonstrated. The fabrication of air-trench splitters is challenging because of the small...
Using air-trench bends, an ultracompact 8 times 8 arrayed waveguide grating (AWG) demultiplexer (200-GHz channel spacing) for wavelength-division multiplexing (WDM) has been designed and fabricated with perfluorocyclobutyl (PFCB) core and clad co-polymers on a polyimide substrate. Compared to a conventional AWG in the same material system, the air-trench bend AWG shrinks the required chip area by...
