摘要： The present invention provides a system and method of optical communications that utilize coherent detection technique and optical orthogonal frequency division multiplexing for phase encoded data transmission. In particular the invention addresses a device and method for digital polarization compensation of optical signals with up to 100 Gb/s transmission rate received via an optical link. The polarization compensation operates in two modes: acquisition mode and tracking mode. The polarization recovery is performed at the receiver side using the received digital signal conversion into frequency domain and separate reconstruction of the polarization state in each spectral component.

摘要： The present invention discloses a transmitter and receiver for optical communications system, which provide compensation of the optical link nonlinearity. M-PSK modulating is used for data embedding in an optical signal in each WDM channel using orthogonal frequency division multiplexing (OFDM) technique. At the receiver side electrical output signals from a coherent optical receiver are processed digitally with the link nonlinearity compensation. It is followed by the signal conversion into frequency domain and information recovery from each subcarrier of the OFDM signal. At the transmitter side an OFDM encoder provides a correction of I and Q components of a M-PSK modulator driving signal to compensate the link nonlinearity prior to sending the optical signal to the receiver.

摘要： This invention provides a tunable delay of an optical signal having a carrier with an angular frequency ω0 and a single side band having a signal band with a median angular frequency ωr. The delay line comprises at least a first, a second and a third integrated resonators coupled sequentially to a waveguide. The first and the second resonators have angular resonant frequencies ω1=ωrΔω and ω2=ωr+Δω respectively, where Δω is a deviation from the median frequency. The third resonator provides a phase delay difference between the phase at the optical carrier ω0 and the phase at the median frequency (Or equal to (ωr−ω0)Td, where Td is the time delay. The device provides an equal group delay to all frequency components in the output signal and also equal phase delay for all frequency components of an RF signal when the optical signal is downconverted at a photodetector. The device may find applications controlling the time delay to antenna elements in a phased array system.

摘要： An image recording and readout device has a light-stimulable phosphor layer for storing a radiation image. The image is read out of the phosphor layer by scanning the layer with a laser beam. A filter is provided between the phosphor layer and the laser to increase the coupling of the laser light into the phosphor layer. The filter passes stimulating laser radiation within an angular acceptance range and reflects stimulating radiation outside the acceptance range.

摘要： This invention removes the need to provide temperature control for an optical time delay chip, which is usually provided by a thermo-electric-cooler, in order to significantly reduce the power dissipation of the device and allow ‘uncooled’ operation. Uncooled operation is achieved by monitoring the temperature of the chip, and changing the tuning of each microresonator within the device in order to continue providing the required time delay as the temperature is varied. This invention takes advantage of the fact that microresonators provide a series of resonant wavelengths over a wide wavelength range, so that the closest resonance wavelength below the operating wavelength can always be tuned up to that wavelength. When the device temperature changes, this is accounted for by both the choice of resonance wavelengths and the tuning for each of the microresonators in the device, in order to keep the correct tunable delay.

The pattern of apertures includes a central aperture, and a plurality of radiation capturing apertures positioned around the central aperture. Each of the radiation capturing apertures has a diameter that is larger than a diameter of the central aperture. The platform further includes a substrate that supports the signal amplifying material and a channel that extends through the substrate. The channel is at least partially aligned with the central aperture that extends through the signal amplifying material.
