Abstract
The optical loss of Unibond waveguides is measured and reported for the first time, using grating couplers. At a wavelength of 1.3 µm, a loss of 0.15 ± 0.05 dB/cm is obtained for TE polarisation. This allows good quality low loss integrated optical circuits to be fabricated at low cost.Keywords
