Abstract
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 a factor
of 20. The decreased size is a factor in reducing the measured thermal shift
to ${-}$0.012 nm/$^\circ$C and decreasing the polarization-dependent wavelength
shift to 1.3 nm.
