摘要： A signal processing device including a light source to emit light at a wavelength which is substantially equal to the carrier wavelength of an optical input signal. An optical resonator provides a filtered signal by optical filtering of the optical input signal. The optical resonator is non-matched with the carrier wavelength of the optical input signal. An optical combiner combines the filtered signal with the emitted light to form an optical output signal. The signal processing device may be adapted to recover the clock frequency of a modulated input signal. The intensity of the output signal exhibits periodic variations at the clock frequency when the resonator is adjusted at least approximately to the predetermined sideband of the modulated input signal.

摘要： Simultaneous recovery of several different clock signals is based on coupling an optical input signal into an optical resonator matched with at least four spectral peaks of the input signal. The input signal having arbitrary polarization is divided by a polarizing splitter into a first signal having horizontal polarization and a second signal having vertical polarization. The polarization of the first signal is rotated 90 degrees such that the polarization of the first signal is parallel to the vertical polarization second signal. Both vertically polarized signals are passed through the same optical resonator in opposite directions, and they are combined after passing through the resonator in order to form an output signal. The spectral separation between the first peak and the second peak is equal to a first clock frequency, and the spectral separation between the third peak and the fourth peak is equal to a second clock frequency. The resonator stores optical energy and provides an output also when the input signal is zero. Thus, the output signal includes a first recovered clock signal which exhibits continuous beat at the first clock frequency, and a second recovered clock signal which exhibits continuous beat at the first clock frequency. Only vertically polarized light is passed through the resonator. Thus, variations in the polarization of the input signal do not require continuous re-adjustment of the resonator.
摘要翻译：几个不同时钟信号的同时恢复是基于将光输入信号耦合到与输入信号的至少四个光谱峰匹配的光谐振器中。具有任意极化的输入信号被偏振分离器分成具有水平极化的第一信号和具有垂直极化的第二信号。第一信号的极化旋转90度，使得第一信号的极化平行于垂直极化第二信号。两个垂直极化信号都以相反的方向通过相同的光学谐振器，并且它们在通过谐振器之后被组合以形成输出信号。第一峰值与第二峰值之间的频谱间隔等于第一时钟频率，第三峰值与第四峰值之间的频谱间隔等于第二时钟频率。谐振器存储光能并且当输入信号为零时也提供输出。因此，输出信号包括以第一时钟频率呈现连续拍频的第一恢复时钟信号和在第一时钟频率呈现连续拍频的第二恢复时钟信号。只有垂直偏振光通过谐振器。因此，输入信号的极化的变化不需要连续重新调节谐振器。

摘要： An optical arithmetic-logical unit [“ALU”] processes one or more combined input signals, which result from a combination of multiple elementary input signals, each of which comprises at least one polarization component. One of the combined input signals is a synchronization signal having a phase and an amplitude. At least one laser has an output and is configured to synchronize with the synchronization signal, wherein the synchronization of the laser with the synchronization input signal generates an output signal, which preserves the phase of the synchronization signal but normalizes its amplitude. Generation of the output signal by said normalization of the synchronization signal provides the ALU with a capability of performing one or more arithmetic-logical operations on the one or more combined input signals.

摘要： A clock recovery device adapted to recover at least one clock signal from an optical input signal. The input signal includes at least one data signal. The clock recovery device-includes a first waveguide, a first optical resonator coupled to the first waveguide, a second optical resonator coupled to the first waveguide, and a combiner to combine signals provided by the first optical resonator and the second optical resonator in order to provide an output signal. A passband of the first optical resonator is matched with a first spectral peak of the input signal, and a passband of the second optical resonator is matched with a second spectral peak of the input signal such that the spectral separation between the first and the second peaks is equal to a clock frequency associated with a first data signal. The optical resonators store optical energy and provide an output also when the data signal is zero. Thus, the output signal includes a first recovered clock signal which exhibits continuous beat at the first clock frequency. The optical resonators are coupled to the same waveguide by evanescent coupling. A high coupling efficiency may be achieved and the use of further optical splitters may be avoided.

摘要： A method and an optical device in all-optical signal processing. It provides a novel way of taking into use the potential bandpass filtering capabilities of an optical complex one-pole resonator by, 1) excitating with at least part of the input signal an optical resonator arrangement that comprises two substantially parallel, independent, complex one-pole resonators arranged in a manner that one of the resonators is matched, and the other one is non-matched with the input signal, and 2) based on polarization separating further from the output of the optical resonator arrangement at least one optical output signal so that both the matched and non-matched resonators contribute to the formation of the output signal. The method and device can be utilized, for example, for optical signal analysis, optical clock recovery, or for producing high-frequency outputs from lower frequency input signals, like e.g. optical microwave generation.

摘要： Apparatus for processing an optical signal carrying symbols. Modulation conversion means converts the optical signal from a first format, wherein each symbol has a unique nominal phase, to a second format, wherein each symbol has a unique combination of nominal phase and nominal amplitude. The modulation conversion means includes a signal splitter for splitting the optical input signal into two optical partial signals, which are directed to respective optical paths. Delay elements cause a mutual temporal difference between the two optical partial signals, which are processed in at least one non-linear regenerator having at least two ports and a gain which depends on the combined signal power directed to the at least two ports. The apparatus directs the optical partial signals from the modulation conversion means to an internal or external photo detector stage in the second format.

摘要： An optical signal regeneration technique includes receiving optical symbols in a phase-modulation format. The received symbols are converted to symbols in a phase/amplitude-modulation format. A first amplitude regeneration, which involves reduction of amplitude noise, is applied to a first symbol pair. A modulation format conversion is performed on the optical signal in the phase/amplitude modulation format after the first amplitude regeneration. A second amplitude regeneration is applied to a second symbol pair, wherein the first and second symbol pairs differ from one another in respect of at least one different feature, which is selected from a group that includes a different nominal phase value assigned to the symbols of the symbol pair and a different temporal distance between the symbols of a symbol pair.
