چکیده
An algorithm to control the biasing of a lithium niobate optical 90° hybrid for coherent detection was embodied in hardware. The control was able to provide optimal biasing with either homodyne or differential detection.

Near quantum-limited, single-shot coherent arbitrary optical waveform measurements.
Four-quadrature spectral interferometry using balanced coherent detection enables single-shot full-field characterization of complex-shaped optical waveforms with near quantum-limited sensitivity. A 90 degrees optical hybrid places a waveform in four-quadrature-phases with a stronger, well-characterized reference pulse. Measurement of the four spectra with an integrating two-dimensional detecto...
متن کاملA Compact Silicon-on-Insulator Optical Hybrid for Low Loss Integration with Balanced Photodetectors
An optical hybrid design based on paired multimode interference couplers in silicon-on-insulator process is investigated. The device exhibits greater than 20 dB CMRR and low phase deviation (<10) over 30 nm in the C-band. The design eliminates the use of optical cross waveguides for integration with balanced photodetectors. Introduction Coherent detection scheme provides high spectral efficienc...

Fig.3 Digital coherent detection with polarization multiplexing, such as dual polarization quadrature phase-shift keying (DP-QPSK), has been attracting considerable attention for constructing 100 Gbit/s transmission systems. The optical front-end for the digital coherent receiver consists of polarization beam splitters (PBSs), optical hybrids, and four sets of balanced photodetectors (PDs). The...

The possibility of inserting an optical klystron on the storage ring of an Iranian Light Source Facility as a Synchrotron Radiation Free electron Laser for coherence harmonic generation in the soft x-ray spectrum has been studied. The study has been performed using the 3D FEL simulation code GENESIS 1.3 and in accordance with the available characteristic parameters of ISLF. Different potential ...
متن کاملA Hybrid Framework for Building an Efficient Incremental Intrusion Detection System
In this paper, a boosting-based incremental hybrid intrusion detection system is introduced. This system combines incremental misuse detection and incremental anomaly detection. We use boosting ensemble of weak classifiers to implement misuse intrusion detection system. It can identify new classes types of intrusions that do not exist in the training dataset for incremental misuse detection. As...
