High output powers and wide range tuning have been achieved in a sampled grating distributed Bragg reflector laser with an integrated semiconductor optical amplifier.Tilted amplifier and anti-reflection facet coating are used to suppress reflection.We have demonstrated sampled grating DBR laser with a tuning range over 38 nm,good wavelength coverage and peak output powers of more than 9 mW for all wavelengths.
High output powers and wide range tuning have been achieved in a balanced grating distributed Bragg reflector laser with an integrated semiconductor optical amplifier. Tilted amplifier and anti-reflection facet coating are used to suppress reflection. over 38 nm, good wavelength coverage and peak output powers of more than 9 mW for all wavelengths.
