Abstract
We demonstrate a 6 frequency digitally tunable laser based on a waveguide grating router fabricated using selective area epitaxy (SAE). The laser wavelengths span from 1.527 to 1.557 μm with 6.4 nm spacings. The bandgap variation in the active layer plane is from 1.352 μm for waveguide ribs to 1.605 μm for the amplifiers. ASE noise is suppressed by 35 db. These results demonstrate the flexibility of SAE technology for building complete photonic circuits.
