Wavelength reuse in a bidirectional UWB over fiber system.
Wavelength reuse in a bidirectional UWB over fiber system using a polarization modulator (PolM) and an electro-absorption modulator (EAM) is proposed and experimentally demonstrated. Since the PolM functions as a special phase modulator that supports phase modulation along the two principal axes with opposite modulation indices and the EAM is a polarization-independent component, the signals du...
متن کاملAll-fiber-optic nonreciprocal modulator.
A new all-fiber-optic nonreciprocal device using two acousto-optic frequency shifters is proposed and demonstrated. When the device was operated as an optical isolator, an extinction ratio of 22 dB was obtained. The device's unique modulation capability is also described.
متن کاملBidirectional coherent classical communication
A unitary interaction coupling two parties enables quantum or classical communication in both the forward and backward directions. Each communication capacity can be thought of as a tradeoff between the achievable rates of specific types of forward and backward communication. Our first result shows that for any bipartite unitary gate, bidirectional coherent classical communication is no more di...
متن کاملMultiplexed fiber Bragg grating strain-sensor system with a fiber Fabry - Perot wavelength filter.
There has been considerable interest recently in the development of fiber-optic sensors based on in-fiber Bragg gratings (FBG's), which can be written into Ge-doped fibers by use of a transverse holographic method.' The use of such elements for distributed strain or temperature sensing in advanced composite or other structural elements and their use as inline reflectors in interferometric syste...
متن کاملSpectrum-, pulsewidth-, and wavelength-switchable all-fiber mode-locked Yb laser with fiber based birefringent filter.
We examined methods of controlling the pulse duration, spectral width and wavelength of the output from an all-fiber Yb laser mode-locked by carbon nanotubes. It is shown that a segment of polarization maintaining (PM) fiber inserted into a standard single mode fiber based laser cavity can function as a spectral selective filter. Adjustment of the length of the PM fiber from 1 to 2 m led to a c...
