摘要： An improved system and method for automated fiber polishing overcomes the limitations of conventional systems and methods. In particular, the present invention provides for continuous determination of the quality of the polish during a polishing procedure. An optical signal is transmitted to a fiber tip, and any back-reflected signal is detected and monitored to determine polish quality. In this manner, automated polishing quality assurance is provided in real time.

摘要： A detector system for a fiber optic component is insensitive to stray light. Specifically, the invention comprises a detector chip, which converts received light into an electric signal. A baffle substrate is positioned over the detector chip. This baffle substrate has a transmission port through which an optical signal is transmitted to the detector chip. As a result, light that is not directed to be transmitted through the port is blocked by the baffle substrate. In this way, it rejects stray light that may be present in the hermetic package. A detector substrate is provided on which the detector chip is mounted. This detector substrate preferably comprises electrical traces to which the detector chip is electrically connected. The detector substrate can further comprise bond pads for wire bonding to make electrical connections to the electrical traces.

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 to the filtered optical signal.

摘要： A system and process for tuning the PER of an electronic system during and/or after its manufacture includes fixtures that allow for the axial rotation of the polarization-maintaining optical fiber relative to the optical system after the optical fiber has been installed in the system. The degradation in the PER ratio of the optical system results from mechanical stresses placed on the fiber during the manufacture of the systems. For example, in the case of optical pump manufacturing, the semiconductor laser is installed on a submount. The PM fiber enters a package through a fiber feedthrough in a ferrule and then is secured down onto the submount, such that the endface of the pigtail is held in proximity to the exit facet of the semiconductor laser. In such systems, highly robust fixturing processes are used, typically such as solder bonding, in which the fiber is metallized and solder bonded either directly or indirectly to the submount. Further, solder is typically applied to seal the ferrule around the fiber since these packages must be hermetically sealed to provide for the long-term stable operation. The solder bonding processes can create asymmetries in the residual stress fields applied around the circumference of the fiber after the solder has cooled. These asymmetric stress fields lead to distortions in the stress-induced birefringent medium of the fiber. This results in coupling between the two polarization modes of the PM fiber, and consequently the degradation of the PER of the system from that expected from the separate components, for which the present invention can compensate.
摘要翻译：在制造期间和/或之后调整电子系统的PER的系统和过程包括在光纤已经安装在系统中之后允许偏振保持光纤相对于光学系统的轴向旋转的固定装置。光学系统的PER比的降低是由于系统制造过程中放置在光纤上的机械应力引起的。例如，在光泵制造的情况下，将半导体激光器安装在基台上。 PM纤维通过套圈中的纤维馈通进入包装中，然后被固定到底座上，使得尾纤的端面保持靠近半导体激光器的出口小面。在这样的系统中，使用高度牢固的固定工艺，通常例如焊接，其中纤维被金属化并且直接或间接地焊接到底座。此外，通常施加焊料以将套圈密封在纤维周围，因为这些包装必须被气密密封以提供长期稳定的操作。在焊料冷却之后，焊接工艺可能在纤维周围施加的残余应力场产生不对称性。这些不对称应力场导致纤维的应力诱导双折射介质的变形。这导致PM光纤的两种偏振模式之间的耦合，并且因此从本发明可以补偿的单独部件所预期的系统的PER降低。

摘要： A semiconductor optical amplifier system comprises a hermetic package. In the typical implementation, this hermetic package is a standard 0.75 inch×0.5 inch package, such as a butterfly package. An optical bench is sealed within this package. A first fiber pigtail enters this package via a feed-through to connect to the bench and terminate above the bench. A second optical fiber pigtail enters the package via a second fiber feed-through to connect to the bench and similarly, terminate above the bench. A semiconductor amplifier chip is connected to the bench to provide amplification. Isolators are further incorporated along with a monitoring diode to yield a fully integrated system.

摘要： A tunable optical filter system 10 has a reference source system 24 that is integrated with the tunable filter 22 on bench 14 and within hermetic package 12. The reference source system 24 is temporally modulated to decrease interference or crosstalk into the scan of the optical signal 64 of interest. Specifically, a system controller 100 energizes the reference source during a reference scan in which the tunable filter 22 is scanned across a spectrum of the optical reference 66. The controller 100, however, lowers, such as simply decreasing or entirely cutting, power to the reference source system 24 during a signal scan, in which the tunable filter 22 is scanned across the optical signal's spectrum. In this way, interference during the signal scan from the reference source system is reduced.

摘要： A system and method for fast peak finding in an optical spectrum prioritizes the information it first generates and how the information is then forwarded from the system to a host computer, for example. A spectrum detection subsystem generates a spectrum of an optical signal. An analog-to-digital converter converts the spectrum into sample data. Finally, a data processing subsystem first detects the spectral locations of peaks in the spectrum using the sample data and then uploads the peak information to a host computer before performing processing to determine the shapes of the peaks and/or noise information for the optical signal, for example. The system is thus able to quickly find some information, such as whether or not channels or carriers are present, at what frequency the carriers are operating, and the carriers' power level, and send this information to the host computer. In contrast, information concerning spectral shape or the noise floor sent later in time.

摘要： A laser system for a spectroscopic catheter system uses multiple semiconductor gain media having gain peaks at different wavelengths. The output from the gain media is preferably coupled into single-mode fiber using conventional opto-electronic packaging techniques. As a result, the laser oscillator source has a spectral output that is wider than the gain bandwidth of a single medium to enable it to access the entire spectrum of interest, which is presently in the near infrared. Moreover, the semiconductor gain media can be packaged in a stable and controlled environment for long-term performance.

摘要： A scanning optical monitoring system and method are appropriate for high speed scanning of a WDM signal band. The system and method are able to identify dropped channels or, more generally, discrepancies between the determined or detected channel inventory and a perpetual inventory for the WDM signal, which perpetual inventory specifies the channels that should be present in the WDM signal assuming proper operation of the network. The system includes a tunable optical filter that scans a pass band across a signal band of a WDM signal to generate a filtered signal. A photodetector then generates an electrical signal in response to this filtered signal. A decision circuit compares the electrical signal to a threshold and a controller, which is responsive to the decision circuit, inventories the channels in the WDM signal.

摘要： A laser system for a spectroscopic catheter system utilizes an overmoded cavity in order to reduce mode hoping induced power fluctuations during wavelength scanning. In the preferred embodiment, a semiconductor gain medium is used to reduce cost. A fiber pigtail is used to define the laser cavity, which has a tight cavity mode spacing of less that 15 Gigahertz. A diffraction grating is used as the tuning element. A cylindrical lens is used to reduce alignment tolerances and thereby increase manufacturability.
