Abstract The implantation of an all-optical eXclusive-OR (XOR) gate run at 160 Gb/s using semiconductor optical amplifiers (SOAs)-based turbo-switched Mach-Zehnder interferometer (TS-MZI) is theoretically investigated and verified. The dependence of the quality factor (QF) on the signal and SOA key operating parameters is examined and assessed, including the impact of amplified spontaneous emission in order to obtain realistic results. A higher QF is obtained when using SOAs-based TS-MZI than when using conventional SOAs-based MZI. More >

Abstract The paraxial ray-tracing model of Fery prism is illustrated in this paper, and the three-order aberration coefficients are calculated. According to the solutions for minimal aberrations, four types of imaging spectrometers are designed based on Fery prism, accommodating for different requirements. The image quality is evaluated to ensure that MTFs are larger than 0.6 at Naquist frequencies, and the spectral resolutions are all higher than 5 nm. The advantages of these imaging spectrometers are analyzed by comparison of the volume, spectral resolution and field of view. The potential competence of Fery prism in hyperspectral imaging More >

Abstract The studies have been carried out on the viability in realizing fully infiltrated solid core photonic crystal fiber based dispersion compensating fiber with suitable high index infiltrate and tapered solid core large mode area fiber for optical communication networks in telecommunication band. The commercial fiber LMA-20 can be made to stretch negative dispersion by suitable fluid infiltration in all air holes of fiber cladding hexagonal structure and can be used as an alternative of existing dispersion compensators (PCFs with low pitch values).
