    • A method of determining polarization dependent characteristic of an optical device under test (10) having at least one input and at least one output, comprises the steps of generating and inputting a stimulus signal (4) to each of a plurality of polarization units (27a, 29b, 127c, 129d), setting each of said input stimulus signals into a unique state of polarization, attaching a characteristic identification portion (27, 29, 127, 129) to each of said input and/or polarized stimulus signals, applying said stimulus signal to said device under test (10) for effecting a response signal of said device under test, receiving and identifying (44, 52) each of said characteristic identification portions from said response signal for tracing each of said polarized stimulus signals within said response signal, deriving a polarization dependent characteristic of said device under test from said traced polarized stimulus signals. The method provides a measurement of polarization dependent loss PDL within one shot of a stimulus signal. For such simultaneous measurements couplers (105, 135) are used. Also for polarization mode dispersion PMD.

    • A laser source with an optical resonator includes a laser gain medium with a low reflective first facet emitting a laser beam within the optical resonator. A wavelength dependent mirror receives the laser beam and reflects back a wavelength separated laser beam. A beam splitter divides the wavelength separated laser beam into a feedback beam directed toward the laser gain medium and a first output beam to be coupled out of the optical resonator. As a first improvement, the laser gain medium includes a second facet which is partly reflective, so that the second facet emits a second output beam of the laser source. As a second improvement, the laser source further includes a mirror arranged in a way that a beam diffracted by the wavelength dependent mirror is reflected back and again diffracted by the wavelength dependent mirror, so that the twice diffracted beam provides the wavelength separated laser beam.

    • This invention relates to a wavemeter and an apparatus for the adjustment of the wavelength of a laser source. The invention proposes a wavemeter comprising an optical component, which generates an optical beam with a wavelength which depends on the optical power of the incident beam to be measured. To increase the precision of the wavelength measurement, the wavemeter is provided with a second measurement channel, whose optical signals are retarded by .pi./2 relative to the optical signals in a first measurement channel. The first and second measurement channels either each comprise a different etalon or the wavemeter comprises a single retardation plate to obtain the desired retardation. After calibration of the wavemeter, the optical power of the beam generated by the optical component is measured, the measured value of the optical power is compared with the power values of the calibration data and the wavelength in the calibration data corresponding to the measured value of the optical power is determined. A controller, such as a PC, compares the measured wavelength with the desired wavelength and automatically adjusts the wavelength of the signals generated by the laser source.
