摘要：

The TM mode suppressibility of DFB lasers with a narrow stripe region is investigated. A waveguide is designed to produce different phase shifts between the TE and TM modes. A threshold gain difference between the TE and TM modes is introduced by a phase shift difference of both modes. A TM and side mode suppression ratio more than 40 dB is obtained under 1.8 Gb/s NRZ pseudorandom pulse modulation. © 1990 IEEE
