Abstract: An optical spectrum analyzer (OSA) 10 sequentially or selectively samples (or filters) a spectral band(s) 11 of light from a broadband optical input signal 12 and measures predetermined optical parameters of the optical signal (e.g., spectral profile) of the input light 12. The OSA 10 is a free-space optical device that includes a collimator assembly 15, a diffraction grating 20 and a mirror 22. A launch pigtail emits into free space the input signal through the collimator assembly 15 and onto the diffraction grating 20, which separates or spreads spatially the collimated input light, and reflects the dispersed light onto the mirror 22. A λ/4 plate 26 is disposed between the mirror 22 and the diffraction grating 20. The mirror reflects the separated light back through the λ/4 plate 26 to the diffraction grating 20, which reflects the light back through the collimating lens 18. The lens 18 focuses spectral bands of light (λ1–λN) at different focal points in space. One of the spectral bands 11 is focused onto a receive pigtail 28, which then propagates to a photodetector 30. A pivoting mechanism 34 pivots the diffraction grating 20 or mirror 22 about a pivot point 36 to sequentially or selectively focus each spectral band 11 to the receive pigtail 28. A position sensor 42 detects the displacement of the diffraction grating 24 or mirror.

Abstract: The present invention provides a method and apparatus for optical spectral power monitoring that employ a time-division-multiplexed detection scheme. The optical spectral power monitoring apparatus of the present invention uses a wavelength-dispersing means such as a diffraction grating to separate a multi-wavelength optical signal into multiple spectral channels and an array of beam-manipulating elements positioned to correspond with the spectral channels. The beam-manipulating elements are individually controllable so as to direct the spectral channels into an optical detector in a time-division-multiplexed sequence. The optical spectral power monitoring apparatus may further employ a polarization diversity scheme, thereby becoming polarization insensitive. This enables the apparatus of the present invention to enhance spectral resolution, while providing improved accuracy in optical spectral power detection. Accordingly, a variety of novel optical spectral power monitors can be constructed according to the present invention, that are well suitable for WDM optical networking applications.
