摘要： New and improved applications of Raman Scattering are disclosed. These applications may be implemented with or without using an enhanced nano-structured surface that is trademarked as the RamanNanoChip™ disclosed in a pending patent. As a RamanNanoChip™ provides much higher sensitivity in SERS compared with conventional enhance surface, broader scopes of applications are now enabled and can be practically implemented as now disclosed in this application. Furthermore, a wide range of applications is achievable as new and improved Raman sensing applications. By applying the analysis of Raman scattering spectrum, applications can be carried out to identify unknown chemical compositions to perform the tasks of homeland security; food, drug and drinking materials safety; early disease diagnosis; environmental monitoring; industrial process monitoring, precious metal and gem authentications, etc.

摘要： A fiber optical circulator in which is a light beam is fed from a fiber of a first port in a dual core glass capillary, then collimated before being passed to a birefringent crystal wherein the light beam is divided into two orthogonal components o and e with a displacement. The State of Polarization (SOP) of components then are changed into the same, perpendicular to the incident plane of the birefringent crystal prism by the group of Faraday Rotator and two Half-Wave Plates (HWP) that have different optical axis orientation and cover o and e components respectively. Then the light components with the same SOP pass into a birefringent prism where they receive angle correction to meet receiving requirement in incident angle for the fiber of port 2 without displacement due to their SOP. This is followed by a second group of HWP and Faraday Rotator that changes the SOP of two components back to orthogonal. The light beam of components then pass into the second birefringent crystal which combines the o and e components together and pass through collimator lens, and are received by optical fiber of the second port. The optical path from the second port to the third port is similar to that described above. However, due to the non-reciprocal property of the Faraday Rotator, the SOP of the two light components from the second port will be in the incident plane of the crystal prism, therefore receive a displacement after the birefringent crystal prism. This displacement combined with angle correction allows the light from the second port is fed into the fiber of the third port. An alternative design uses a pair of glass prism and a plane crystal to replace the function of crystal prism in the preferred embodiment.

摘要： A fiber optical circulator wherein optical fibers of three ports share one glass capillary, one collimator lens and one walk-off crystal. Three optical fibers lie on a plane in a glass capillary that is aligned with a collimator lens concentrically. A light fed into the fiber of port 1, which is off optical axis of collimator lens, is collimated with an angle &thgr; to the axis of collimate lens. The collimated beam is divided into two orthogonal components by a first crystal. A device group consisting of one Faraday rotator and one pair of Half Wave Plates transfers the State Of Polarization (SOP) of two components into the same. The angled part of a combined prism bent both beams to be parallel to optical axis of system. The lights pass through a second crystal without displacement due to their SOP. Their SOP receive 90° rotations by a round trip in followed Faraday rotator with help of a reflection film on the backside or a mirror. The light components receive a displacement onto optical axis after the second crystal due to their rotated SOP, pass through the flat part of combined prism, changes their SOP with help of the group of Rotator and wave plate, combined into one beam by the first crystal, and is focused into the fiber of port 2 by collimate lens. The process of port 2 to port 3 is similar to above. The light fed into fiber of port 2 is collimated to be parallel to the optical axis. The collimated beams pass though all parts then reflected by the reflection film or mirror. The light beam in return path receives a displacement by the second crystal and bending angle by the angled part of combined prism. The light is finally focused into the fiber of port 3 by the collimate lens. Since this circulator requires less optical parts, it achieves compact size and low cost simultaneously.

摘要翻译： 一种光纤循环器，其中三个端口的光纤共用一个玻璃毛细管，一个准直透镜和一个离去晶体。 三根光纤位于与准直透镜同心对准的玻璃毛细管中的平面上。 馈送到位于准直透镜的光轴的端口1的光纤的光被准直与准直透镜的轴线成角度θ。 准直束由第一晶体分成两个正交分量。 由一个法拉第旋转器和一对半波片组成的器件组将两个组件的极化状态转移到同一个。 组合棱镜的倾斜部分将两个梁弯曲成平行于系统的光轴。 由于它们的SOP，灯光通过第二个晶体而没有位移。 他们的SOP通过后面的法拉第旋转器的往返接收90度旋转，帮助背面的反射膜或镜子。 光分量由于旋转的SOP而在第二晶体之后在光轴上接收位移，穿过组合棱镜的平坦部分，借助于旋转器和波片的组，改变其SOP，由第一晶体组合成一个光束 ，并通过准直透镜聚焦到端口2的光纤。 端口2到端口3的过程与上述类似。 进入端口2的光纤的光被准直以平行于光轴。 准直光束通过所有部分，然后被反射膜或反射镜反射。 返回路径中的光束由组合棱镜的倾斜部分接收第二晶体的位移和弯曲角度。 光通过准直透镜最终聚焦在端口3的光纤中。 由于该循环器需要较少的光学部件，因此同时实现了紧凑的尺寸和低成本。
