Spatial and spectral filtering of tapered lasers by using tapered distributed Bragg reflector grating
文献摘要：
A 1040 nm tapered laser with tapered distributed Bragg reflector(DBR)grating is designed and fabricated.By designing the grating with tapered layout,the tapered DBR grating exhibits the scattering effect on side backward-traveling waves,thus achieving additional suppression of parasitic oscillation.Under the suppression of parasitic oscillation,the spatial and spectral characteristics of the tapered laser are improved.The experimental results show that a near-Gaussian far-field distribution and a kink-free P-I characteristics are achieved,and a single peak emission with a wavelength of 1046.84 nm and a linewidth of 56 pm is obtained.
