Abstract :
Enhanced performance in fiber Bragg grating-stabilized laser diode designs using polarization-maintaining fiber pigtails requires tight control of polarization extinction ratio. Polarization extinction ratio (PER) affects device power stability, photocurrent behavior, and spectral characteristics. In this paper, the impact of PER on the final device performance is quantified and significant performance improvement when PER is maintained at or above 20 dB is demonstrated.
