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.

摘要： An optical monitoring system provides for out-of-band calibration. As a result, calibration can be performed simultaneously with monitoring. This can be used to accomplish faster and/or more accurate scanning. In addition, the need for complex switching and/or multiplexing capabilities can be avoided. The system comprises a signal source of an optical signal having spectrally separated channels, which are distributed within a spectral band, such as a WDM signal. A reference source generates a reference signal outside of the spectral band. A tunable filter filters the optical signal and the reference signal. A reference signal detector then detects the filtered reference signal, while an optical signal detector detects the filtered optical signal.

摘要： A multi fiber optic medical probe comprises at least two optical fibers. There are side-firing terminations for the at least two optical fibers. Further, beam-shaping apertures are provided for controlling light propagating between the side-firing terminations and a region lateral to the probe. The provision of the at least two optical fibers allows for multiple optical signals to be transmitted to and/or from the target area within the patient. The side-firing terminations allow for the interrogation of regions that are adjacent to the probe, i.e ., extending in a direction parallel to the insertion direction or longitudinal axis of the probe. The beam shaping apertures are provided for controlling light propagating between the side-firing terminations and the region lateral to the probe, in order to control the shape of the emitted beam and also, the direction from which light is collected.

摘要： A system for assessing the quality of the optical connection between a catheter and a console is described that avoids the necessity of a calibration port, although one can still be provided if desired. It operates by monitoring the level of light returning from the catheter head and specifically the degree to which this returning light is attenuated. Reflections will arise at the catheter head's optical window due to the discontinuity between the refractive index of the window and that of air or other medium into which the head is inserted. Since the refractive index of the optical window is known and with the head in a known medium such as air, the level of reflection is known. This enables a controller in the console to calculate the round trip loss and thus monitor the loss in the catheter-console interface.
摘要翻译：描述了用于评估导管和控制台之间的光学连接的质量的系统，其避免了校准端口的必要性，尽管如果需要仍可提供校准端口。它通过监测从导管头返回的光的水平，特别是该返回光被衰减的程度来操作。由于窗口的折射率与插入头部的空气或其他介质的折射率之间的不连续性，导管头的光学窗口将产生反射。由于光学窗口的折射率是已知的，并且在诸如空气的已知介质中的头部，所以反射的水平是已知的。这使得控制台中的控制器能够计算往返损失，从而监测导管 - 控制台界面中的损耗。

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 (28) 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 semiconductor optical amplifier system (100) comprises a hermetic package (112). In the typical implementation, this hermetic package (112) is a standard butterfly, DIP or miniDIL package. An optical bench (116) is sealed within this package (112). A first fiber pigtail (118) enters this package via a feed-through to connect to the bench (116) and terminate above the bench. A second optical fiber pigtail (120) enters the package (112) via a second fiber feed-through to connect to the bench (116) and similarly terminate above the bench. A semiconductor amplifier chip (102) is connected to the bench (116) to provide amplification. Isolators (128, 130) are further incorporated along with a monitoring diode (126) to yield a fully integrated system.

摘要： A channel monitoring system has improved the spectral filtering accuracy by using a tunable filter system that transmits the optical signal through serial filter cavities. This has the effect of dramatically narrowing the filter's transfer function. Moreover, it improves side mode rejection. In the preferred embodiment, the filter is implemented in a double-pass configuration.
