摘要： An optical receiver adapted to apply multiple-sampling processing to an optical duobinary signal received over a transmission link in an optical communication system. In one embodiment, the receiver has an optical-to-electrical signal converter coupled to a decoder adapted to process an electrical signal generated by the converter to generate a bit sequence corresponding to the optical signal. To generate a bit value, the decoder first obtains two or more bit estimate values by sampling the electrical signal within a corresponding signaling interval two or more times. The decoder then applies a logical function to the bit estimate values, which produces the corresponding bit value for the bit sequence. Advantageously, embodiments of the present invention improve overall back-to-back (i.e., source-to-destination) system performance, e.g., by reducing the number of decoding errors associated with timing jitter and/or spontaneous beat noise in the received optical signal.

摘要： The inventors propose herein a switch fabric architecture that allows broadcasting and fast channel access in the ns-range. In various embodiments of the present invention, 10 Gb/s receiver modules are based on a novel heterodyne receiver and detection technique, which is tolerant to moderate wavelength drifts of a local oscillator. A gain clipped electrical amplifier is used in the novel receiver as a rectifier for bandpass signal recovery.

摘要： An optical receiver adapted to apply multiple-sampling processing to an intermediate frequency (IF) signal generated based on heterodyne detection of an optical communication signal. In one embodiment, the receiver has an optical-to-electrical signal converter coupled to a signal decoder adapted to process the IF signal generated by the converter to generate a bit sequence corresponding to the optical communication signal. To generate a bit value, the signal decoder first obtains two or more sample-bit values by sampling the IF signal two or more times per signaling interval. The decoder then applies a logical function to the sample-bit values, which produces the corresponding bit value for the bit sequence. Due to the multiple-sampling processing, a receiver of the invention does not require the time-consuming fine wavelength tuning of its local oscillator, which advantageously reduces the channel switching time achieved in the receiver compared to that in prior-art heterodyne receivers.
摘要翻译：一种适于对基于光通信信号的外差检测产生的中频（IF）信号应用多采样处理的光接收器。在一个实施例中，接收器具有耦合到适于处理由转换器产生的IF信号的信号解码器的光电信号转换器，以产生对应于光通信信号的位序列。为了产生位值，信号解码器首先通过每个信令间隔对IF信号进行两次或更多次采样来获得两个或更多个采样比特值。然后，解码器将逻辑功能应用于采样比特值，其产生比特序列的相应比特值。由于多次采样处理，本发明的接收机不需要对其本地振荡器进行耗时的精细波长调谐，与现有技术的外差接收机相比，有利地降低了在接收机中实现的信道切换时间。

摘要： Simultaneous tolerance of system nonlinearities and chromatic dispersion in an optical transmission system using return-to-zero (RZ) duobinary signaling is achieved by filtering the received signal in the optical domain with a bandpass filter having a bandwidth B substantially equal to the bit-rate of the RZ-duobinary data signal. The use of an optical bandpass filter in a receiver for RZ-duobinary signals maintains the expected tolerance of system nonlinearities and simultaneously increases significantly the chromatic dispersion tolerance of the signals.

摘要： An integrated broadband polarization controller is based on planar waveguide technology. The integrated broadband polarization controller emulates the polarization control function of an existing single channel polarization controller in a device that can be built in planar waveguide technology, and is expanded from single channel operation to broadband channel operation by designing the control degrees of freedom to be wavelength selectively addressable.
