Abstract :
A small and low-loss athermal AWG is demonstrated based on super-high-Δ waveguides. Resin-filled trenches are formed in the slab region to compensate for the temperature-dependent wavelength shift. Small wavelength shift of 0.03 nm is achieved for the temperature range 0-65°C with almost no spectral degradation.
