摘要： Improved methods and systems for routing and aligning beams and optical elements in an optical device include a multiplexing device (100) and/or a demultiplexing device, which includes an optical alignment element (OAE). The OAE can be configured to substantially compensate for the cumulative alignment errors in the beam path. The OAE allows the optical elements in a device, other than the OAE, to be placed and fixed in place without substantially compensating for optical alignment errors. The OAE is inserted into the beam path and adjusted. This greatly increases the ease in the manufacturing of optical devices, especially for devices with numerous optical elements, and lowers the cost of manufacturing. The multiplexing and/or demultiplexing device can reside within a standard small form factor, such as a GBIC. The devices fold the paths of the traversing beams with a geometry which allows a small package.

摘要： A monitoring system has the capability to monitor multiple signal bands simultaneously. Specifically, in one embodiment, the monitoring system can simultaneously monitor the C- and L- bands. As a result, the time to scan through the spectral band can be reduced by half. The system comprises a signal source for an optical signal having spectrally separated channels distributed within a first spectral band and a second spectral band. A tunable filter filters this optical signal. A dichroic filter separates the first spectral band from the second spectral band in the optical signal, which has been filtered by the tunable filter. Thereafter, first and second optical detectors detect the respective spectral bands in the filtered optical signal.

摘要： A bi-directional polarization independent optical isolator (700) simultaneously transmits two separate signal rays in opposite forward directions and simultaneously suppresses backward transmission of each signal ray in its respective reverse direction. The separate signal rays may comprise either two wavelength bands completely separated by wavelength or two sets of wavelengths, such that wavelengths of the two signal rays are interspersed in alternating fashion. The bi-directional polarization independent isolator includes a birefringent polarization separation/combining element (703), a reciprocal optical rotation element (704), a lens (707), a reflective element (709, 710), and a reciprocal optical rotation element (711). The reflective element comprises either a mirror/waveplate assembly (708) or a non-linear interferometer. Four fibers or optical ports are optically coupled to the isolator and may be configured such that either single-stage bi-directional isolation is accomplished for each of two fiber transmission lines or double stage bi-directional isolation is accomplished on a single fiber transmission line.
