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.
