We propose a novel hollow optical waveguide with thin film coating for temperature insensitive photonic devices. Low-loss and polarization insensitive propagation characteristics are predicted. We fabricated a hollow waveguide with metal coated walls on GaAs substrate. The propagation loss was 2.6 dB/cm and 7.3 dB/cm for TE and TM modes, respectively.
