Abstract :
The authors have fabricated InP/GaInAsP rib waveguides with losses as low as 0.18 dB/cm for the TE polarisation and 0.26 dB/cm for the TM polarisation. The length of the waveguides was 28 mm. These losses are measured with the Fabry-Perot method and repeated for different lengths of the waveguide for determining the reflection coefficient.
