Their topics include a physical layer perspective on optical transport networks, the
phase encoded optical code division multiplexing access system, optical time domain multiplexing-wavelength division multiplexing (OTDM-WDM) system components modeling, optimizing parameters for optimal performance, and network performance analysis with nonlinear effects.
"For PM-QPSK, we designed and integrated narrow-linewidth lasers that detect the
phase encoded data very efficiently."
In a paper published in the journal Nature Photonics, the Phasors project announced the first practical phase sensitive amplifier and phase regenerator for high-speed binary phase encoded signals.
ORC deputy director and Phasors director Professor David Richardson said: "This is an important first step towards the practical implementation of all-optical signal processing of phase encoded signals, which are now being exploited commercially due to their improved data carrying capacity.
ICL has developed a new
phase encoded, 9-track magnetic tape system for use with its System 4 computers.
An authentication system using a correlator that correlates an input with a reference wherein at least one of the input and reference comprises a phase volume mask having structures, preferably points, that are each less than about six microns in size and can have an aspect ratio (AR) greater than 1:1 so as to produce a
phase encoded random pattern having millions of combinations in a mask that is as small as one square millimeter.
When using this sequence as a fast scanning technique, small flip angle pulses are used to read out a series of stimulated echoes that are separately
phase encoded.[20] The high-speed STEAM technique reduces motion artifact without using strong gradients.
Scientists on the PHASORS project announced the development of the first practical phase sensitive amplifier and phase regenerator for high-speed binary
phase encoded signals.
