Improved fibre grating lasers using large spot, curved waveguide semiconductor reflective amplifiers

摘要

High performance operation is reported of fibre grating lasers which have a large spot, curved waveguide semiconductor reflective amplifier as the gain block. Devices incorporating both uncoated and antireflection coated chips show good linearity and temperature stability. Direct modulation at rates to 2.5 Gbit/s is demonstrated.
