中文摘要	a ingaasp/inp self-aligned, native oxidized buried heterostructure (bh) distributed feedback (dfb) laser is proposed. it is as easy to process as the ridge waveguide dfb laser and has superior performance. the current aperture can be easily controlled without selective regrowth. the laser exhibits a low threshold of 5.0 ma with 36 db side mode suppression ratio at the emission wavelength of 1.562 mu m. it emits in a single lobe with full width at half maximum angles of 33.6 degrees and 42.6 degrees for the lateral and vertical fields, respectively. its beam is more circular than that of the as-grown bh laser because the lower refractive index of oxide compared to the as-grown layer and results in a larger lateral optical confinement. its characteristic temperature (t-0) is 50 k at room temperature but increases in value at the higher temperature range.
