摘要：

The dependence of the spectral linewidth on the phase shift position (PSP) of a phase-shifted distributed-feedback (DFB) laser diode has been investigated theoretically, using the coupled wave model. In particular, the analysis has been performed to find an optimum PSP so as to minimize the spectra) linewidth of the laser diode. This optimum PSP has been compared to that obtained by maximizing the stability of the laser oscillation. Since both narrow spectral linewidth and good stability are essential for the light source in coherent optical communications, the analysis reveals the suitability of using phase-shifted DFB laser diodes in coherent transmissions. © 1990 IEEE
