Abstract :
We present a widely tunable laser consisting of a semiconductor optical amplifier (SOA) glued directly to a silica waveguide grating router, that can be packaged without submicrometer alignments, air gaps, or SOA vertical spot-size conversion. However, issues regarding thermooptic power consumption and modal stability remain to be solved.
