The polarization state of a light wave is changed by a fiber polanrzation retardation device constructed by a method including employment of a pair of clamping fixtures, and a series of steps including clamping, cleaving, splicing, releasing, clamping, and cleaving, so as to achieve precise optical fiber lengths to achieve a desired polarization retarding device.

Method for fabrication of an all fiber polarization retardation device

The invention includes a ferrule having a layer of material on an inner surface of a hole therein which is selected to be preferentially softenable relative to the bulk material of the ferrule. The ferrule according to the present invention can be fused to optical fibers, capillaries and the like while reducing deformation of the fused component and the ferrule.

Connector ferrule and method of sealing

The invention includes a ferrule having a layer of material on an inner surface of a hole therein which is selected to be preferentially softenable relative to the bulk material of the ferrule. The ferrule according to the present invention can be fused to optical fibers, capillaries and the like while reducing deformation of the fused component and the ferrule. A fiber Bragg grating device and a flow cell device are also provided.

In many optics applications, it is desirable to retard the polarization of a light wave, i.e., to change the polarization state of a light wave. In a method for retarding polarization of a light wave, a first linear polarization-maintaining fiber having a first beat length is spliced to a second polarization-maintaining fiber having a high birefringence and a second beat length. The second fiber is then cleaved to a length which is a fraction of the second beat length. The first fiber and the second fiber may be secured in a removable or permanent capillary. A light wave is transmitted into the first fiber and the polarization state of the light wave is determined. To adjust the polarization state, the second fiber may be lapped against an abrasive substance. The second fiber may be repeatedly lapped until a desired polarization state is achieved. In an alternate method, a first linear polarization-maintaining fiber is spliced to a second polarization-maintaining fiber having a high birefringence and a beat length. The second fiber is cleaved to a length which is a fraction of the beat length and a third fiber is spliced to the second fiber. A light wave is transmitted through the fibers and the polarization state of the light wave is determined. All or part of the second fiber may be heated to adjust the polarization state of a light wave. The second fiber may be repeatedly heated until a desired polarization state is achieved.

An Integrated Optics Chip (IOC) package for an IOC, including a base having an upper support surface having a first raised surface and a dielectric gel disposed on the first raised surface of the base and adapted to couple to the IOC. The dielectric gel is sufficiently compliant to minimize stresses from structural changes in the base, accommodate a thermal mismatch between the IOC and the base, and reduce vibration. A first adhesive may be applied to a platform integral to the base that is sufficiently rigid to prevent the IOC from separating from the dielectric gel during vibration. A second adhesive may be applied on a second raised surface of the base to provide strain relief to the leads of the IOC. Advantages include the elimination of several components and manufacturing steps, improved strain relief and vibration dampening, as well as manufacturing time and cost savings.

Submountless integrated optics chip package

A fiber optic gyroscope that includes an improved winding transition section otherwise known as a 'jog zone'. The improved jog zone reduces losses due to micro-bends and cross-coupling in the fiber optic coil. The reduced losses enable a more accurate measurement of rotation rate of the fiber optic coil, while minimizing unwanted phase-shifts that can cause false readings in the fiber optic gyroscope.

Job zone for a high performance navigation grade rate sensing coil

A housing for fiber optic components reduces stress on optical fibers and protects the components from environmental shock and vibration. The housing includes a protective body having a receiving space wherein the fiber optic component is positioned. A rigid adhesive applied to the fibers in a specific stress reducing profile near the ends of the receiving space secures the component out of contact with the wall of the receiving space without inducing stress on the jacketless optical fibers. A gel support material fills the receiving space surrounding the component and providing vibration isolation. The invention is particularly uses for housing fiber optic couplers which are subject to shock, vibration, and temperature extremes.

Fiber-optic coupler package

A fiber optic coupler includes at least two optical fibers having a coupled region and at least one lead portion extending therefrom. The optical fibers have a protective jacket thereon. The protective jacket is removed from the coupled region and from a region of the at least one lead portion adjacent the coupled region resulting in a jacketless coupled region, at least one jacketless lead portion and at least one jacketed lead portion. The fiber optic coupler further includes a protective body having a receiving space therein for receiving the coupled region. The protective body has at least one entrance from which said jacketed lead portion emerges. A rejacket material at least partially surrounds a length of the jacketless lead portion adjacent the jacketed lead portion resulting in a rejacketed lead portion. An adhesive material at least partially about a length of the jacketed lead portion at the entrance and at least partially about the rejacketed lead portion secures the length of the jacketed lead portion and rejacketed lead portion to the protective body.
