A loss-coupled 1550 nm distributed feedback (DFB) laser diode with automatically buried absorptive InAsP layer for the application to radio-over-fiber network was experimentally investigated where the automatically buried layer in the epitaxial growth reduced the process steps in loss-coupled DFB laser fabrication. It showed linearity in electro-optical conversion characteristics with reduced third order intermodulation distortion of -70 dBc which is comparable to the previous results of DFB lasers as the optical power increases to 5 mW under two-tone test at 1.8 GHz bands.
