摘要： A polarization independent switch, using polarization diversity for converting the input beams to a single defined polarization direction, followed by wavelength dispersion to spread the individual wavelength channels over a pixilated switching device. This may be a polarization rotation element whose setting can be controlled by means of an applied electronic signal. This may either leave the polarization direction unchanged, or it may rotate it such that it is essentially orthogonal to the polarization of the input beam exiting the polarization diversity components. The beam then proceeds to a birefractive wedge element which refracts light having the two orthogonal polarizations to different extents, thus separating the beams according to the control signal applied to the polarization rotation element through which each wavelength component of the beam passed. The beams may thus be directed to different ports according to the control signal setting. 2 x 1 switch configurations are shown.

摘要： A system for enabling the accurate determination of the lasing wavelength of a tunable wavelength locked laser. The locker feedback loop includes an additional external fixed filter having a distinctive wavelength feature at a known wavelength, such as a sharp cut-on or cut-off point, or a well defined notch. This external filter is constructed of materials having high mechanical and thermal stability, and is maintained in a temperature stable environment, such that its wavelength characteristics are well defined and do not change more than a fraction of the grid spacing with environmental or aging conditions. The fixed external filter can have substantially higher wavelength stability than a liquid crystal tunable filter. The position of the distinctive wavelength feature is accurately known. The additional external filter is incorporated into the wavelength locker feedback loop, such that its transmissive properties are impressed on the detector in that loop.
