Fabrication of low-loss integrated optical corner mirrors.
Waveguides and corner mirrors are fabricated in InGaAsP/lnP. Properly aligned mirrors have a loss of 0.8 dB per reflection. This result is obtained by improved waveguide and mirror quality (surface roughness). Measured additional losses that are due to misalignment agree well with calculated values when a simple transformation method is used.
