We propose and demonstrate a new all-fiber-optic nonreciprocal device without using magnetic field and Faraday effect. The device is based on a nonreciprocal phase shift produced by a set of acousto-optic frequency shifters, that is used in an interferometer to form a nonreciprocal intensity transmitter. The device is a Mach-Zehnder interferometer with two reciprocal frequency shifters in one of the ...

An attractive method for producing reciprocal phase shift is to use a pair of identical nonreciprocal phase shifters with circulators at input and output, as shown in Figure 1. In this scheme, signals passing from left to right are sent through the lower phase shifter, while signals passing from right to left are sent through the upper phase shifter. By ...

Phase Retrieval with Application to Optical Imaging
We propose and demonstrate a new all-fiber-optic nonreciprocal device without using magnetic field and Faraday effect. The device is based on a nonreciprocal phase shift produced by a set of acousto-optic frequency shifters, that is used in an interferometer to form a nonreciprocal intensity transmitter. The device is a Mach-Zehnder interferometer with two reciprocal frequency shifters in one of the arms, that shift the optical frequency up and down.
An attractive method for producing reciprocal phase shift is to use a pair of identical nonreciprocal phase shifters with circulators at input and output, as shown in Figure 1. In this scheme, signals passing from left to right are sent through the lower phase shifter, while signals passing from right to left are sent through the upper phase shifter. By switching the phase shifters in a complementary manner, equal variable insertion phases can be provided for either direction of propagation. This approach to achieving reciprocal phase shift yields the desirable bandwidth, figure of merit, and temperature stability advantages of nonreciprocal phase shifters, except that it is more complicated and has the additional losses of the input and output circulators. However, the added complexity can be significantly reduced by employing a dual-mode transmission line in which the two nonreciprocal phase shifters occupy the same physical space. It is the purpose of this paper to describe the principle of operation, physical realization, and performance parameters for a reciprocal phase shifter of this latter type.
The paper deals with investigation of polarization in different types of laser diodes which can be used as sources of optical radiation for atmospheric optical communication systems. Results of laser beams study for different types of laser diodes and typical wavelengths are presented in the paper. Also possibility of laser beam transformation, from the type of polarization point of view, was studied as idea for improvement the immunity of laser beam towards the atmosphere conditions, mainly turbulence. Polarization properties of laser diodes were presented in the form of polar intensity diagrams and Stokes vectors represented on the Poincaré sphere.
Summary from only given. We present results of experiment aiming to generate smooth spectrum in the range 500-1100 nm with the use of chirp and polarization adjustments of the incident pulse as well as its duration. No numerical simulations are known on this subject mainly because of the difficulties in 3D modelling the complex PCF-structure; as well as no systematical experimental results are known. The polarization dependence can be explained with the multifrigency of the PCF, due to its broken azimuthal symmetry.
A polarization scrambler with a single electrooptic waveplate is presented. A preliminar version allowed to detect 680fs of PMD at 40Gbit/s within 9.6us. With a 2nd waveplate a scrambler independent of input polarization was realized.
A rotatable ferrite nonreciprocal quarter-wave plate is coupled at each end to the square waveguide ports of two septum polarizers. The four-port junction that is created has the properties that: (a) transmit and receive signals appear at different ports of the input septum polarizer; (b) equal-amplitude power division of the transmit signal is performed with arbitrary phase difference between the two output ports; and (c) equal-amplitude signals entering the output ports with the same phase difference will be summed and coupled to the receive port of the input septum polarizer. Measured data are presented for an experimental structure
We demonstrate the generation of polarization-entangled photon pairs in an integrated AlGaAs waveguide using spontaneous four-wave-mixing. State tomography is performed, with the concurrence found to be 0.97±0.01, and fidelity to a maximally-entangled state to be 0.97.
A wavelength selective optical isolator is proposed. Being different from conventional isolators, a well-designed wave plate is employed and works together with the Faraday rotator. Different wavelengths thus experiences different phase retardation so that wavelength-dependant polarization states are obtained for bidirectional beams. A (1.49 μm, 1.31 μm) wavelength selective isolator is demonstrated, which means 1.49 μm light only may propagate along one-direction why the opposite wave is only for 1.31 μm light. Over 60 dB optical isolation is obtained, which has promising applications in access optical networks.
