A comparison of approaches for ultra-low-loss waveguides

We compare ultra-low-loss silica waveguides with PECVD SiO 2 , borophosphosilicate glass (BPSG), and wafer-bonded thermal oxide upper claddings. We demonstrate fiber-like (0.045 dB/m) total propagation loss in planar waveguides with bonded thermal oxide upper claddings.
