摘要： The present invention is directed to the creation of optical waveguiding devices from standard optical fibers by the creation of zones of permanently altered refractive index characteristics therein. A high intensity femtosecond laser beam is focused at a predetermined target region in the fiber so as to soften the glass material at the target region. After aligning the focal region with the target region in the fiber there will be relative movement between the focal region and the fiber, which has the effect of sweeping the focal region across the fiber in a predetermined path, so as to create a secondary waveguide path. A portion of the light traveling along the core is removed from the core along the secondary waveguide path such that the device can be utilized as an attenuator, an optical tap, or a polarimeter.

摘要： The present invention is directed to the creation of zones of permanently altered refractive index characteristics in glass waveguiding devices, including optical fibers and optical waveguides pre-existed in a glass substrate. Such zones in which the refractive index has been permanently altered are created in glass using a very high intensity laser beam which is produced by focusing the light output from an ultrafast pulsed laser at a predetermined target region in the glass. The preferred laser is a Ti:Sapphire amplified, frequency-doubled Erbium-doped fiber laser system, providing light pulses of approximately 100 femtosecond duration, each with an energy of between about 1 nanojoule and 1 millijoule, and preferably at a pulse repetition rate of between 500 Hz and 1 GHz. The repetition rate is chosen to deliver pulses faster than the thermal diffusion time over the dimensions of the volume element being modified. This latter process is to accumulate heat to the point of liquefying the material in order to increase material compliance to the femtosecond writing process and increase the subsequent thermal barrier to relaxation of the written structural element and thereby increase the lifetime of the device or structural function. One or more zones of permanently altered refractive index characteristics can be formed in a waveguiding device, such as an optical fiber by utilizing a focused, pulsed, laser light source which generates a focal region having an intensity greater than the threshold for inducing permanent refractive index changes in the device. The focal region is aligned with the device and relative movement between the focal region and the device has the effect of sweeping the focal region across the device in a predetermined path. The result is a zone within the device in which the refractive index characteristics of the device have been permanently altered so as to control amplitude, phase, spatial propagation or polarization states of light within the material.

The nonlinear crystal is configured to receive at least one input laser beam at the first end face and output a frequency converted beam at the second face. A beam waist of the at least one input laser beam is positioned between the first end face and the second end face during a frequency conversion process. The device also includes a second crystal having a first end face bonded to the second end face of the nonlinear crystal and a second end face opposed to the first end face. A beam diameter of the frequency converted beam at the first end face of the second crystal is less than a beam diameter of the frequency converted beam at the second end face of the second crystal.
