Polarization-Maintaining Filters
II-VI Finisar
Finisar Corp. has introduced two single-polarization programmable optical filters. The WaveShaper 1000S/SP and 1000M/SP are polarization-maintaining filters that provide full control of the amplitude and phase spectra across the entire C-band.
They are designed for pulsed laser applications in medical and materials processing as well as for testing of advanced optical communication systems. They precisely control the shape and timing of a laser pulse, enabling shorter and more stable pulses and increasing manufacturing accuracy and throughput.
Advanced optical communication systems incorporating polarization multiplexing or coherent technologies benefit from the WaveShaper 1000/SP because it enables independent setting of the signal characteristics in each polarization.
The instruments are suitable for use in applications where polarization control is critical, such as polarization-multiplexed communication systems and seed lasers for high-power pulsed fiber lasers.
