Selective launching of higher-order modes into an optical fiber with an optical phase shifter.
We demonstrate a simple, effective technique for launching higher-order modes into a double-mode optical fiber by using an optical phase shifter at the input end. The suppression of the lowest-order mode was measured (but not limited) to be 27 dB.
متن کاملA multicore optical fiber for distributed sensing
With advancements in optical fiber technology, the incorporation of multiple sensing functionalities within a single fiber structure opens the possibility to deploy dielectric, fully distributed, long-length optical sensors in an extremely small cross section. To illustrate the concept, we designed and manufactured a multicore optical fiber with three graded-index (GI) multimode (MM) cores and ...
متن کاملAll-fiber Raman Probe using Higher Order Modes
We demonstrate the first all-fiber Raman probe utilizing higher order modes for the excitation. The spectrum of cyclohexane is measured using both the fundamental mode as well as in-fiber-generated Bessel-like modes. © 2013 Optical Society of America OCIS codes: 060.2370, 060.4370.
متن کاملHigher Order Sliding Modes
One of the most important control problems is control under heavy uncertainty conditions. While there are a number of sophisticated methods like adaptation based on identi cation and observation, or absolute stability methods, the most obvious way to withstand the uncertainty is to keep some constraints by "brutal force". Indeed any strictly kept equality removes one "uncertainty dimension". Th...
متن کاملFiber Optic Sensor Embedment Study for Multi-Parameter Strain Sensing
The fiber optic sensors (FOSs) are commonly used for large-scale structure monitoring systems for their small size, noise free and low electrical risk characteristics. Embedded fiber optic sensors (FOSs) lead to micro-damage in composite structures. This damage generation threshold is based on the coating material of the FOSs and their diameter. In addition, embedded FOSs are aligned parallel t...
