Abstract and Figures We present a reconfigurable ultra-broadband mode converter, which consists of a two-mode fiber (TMF) and pressure-loaded phase-shifted long-period alloyed
This apodization scheme is applicable to all types of fibre gratings, written by direct replication by a scanning or a static beam, or by use of any other interferometer
However, by coating the optical fiber with an appropriate polymer, transverse pressure is converted to axial strain, thereby increasing the pressure sensitivity of
Chirped Fiber Bragg Gratings "Chirp" is the high-pitched varying sound emitted by certain birds and bats. Gratings that have a nonuniform period along their length are therefore known as chirped. Chirp
