Propagation losses as low as 0.24±0.06 dB/cm are demonstrated for single-mode, GaInAs/InP multiple quantum well rib waveguides at 1.52 μm wavelength. We show that reproducibly low losses (≤0.6 dB/cm for rib widths ≥3 μm) can be maintained over a large chip area (9.4×5 mm2). Origins of the loss are discussed.
