Abstract

Feature Issue on Optical Performance Monitoring (OPM)

Simultaneous monitoring of power, wavelength, and channel number for a tunable laser is demonstrated by use of a combination of an optical isolator, an etalon, a polarizer, and photodiodes. The mode hopping and incomplete-tuning problems that might arise in tuning the laser can be detected with the proposed approach. The spectral response of the monitoring module can be adjusted to match the wavelength-tuning range. The spectral adjustment can be performed by rotating the input polarization or the output polarizer. It can also be tuned by rotating the second stage if a two-stage isolator is used. We demonstrate experimentally the feasibility of this approach by use of discrete fiber-pigtailed components.
