    • Consistent with the present disclosure, data, in digital form, is received by a transmit node of an optical communication system, and is then provided to a modulator that, in turn, modulates light, received from an optical source at one of a plurality of periodically and preferably minimally spaced wavelengths. The plurality of periodically spaced wavelengths or carriers are grouped together with minimal carrier spacing, to form a superchannel. The carrier spacing between adjacent carriers is determined by detecting a beat frequency of a combined optical signal that includes the outputs of two adjacent optical sources. The beat frequency corresponds to a frequency difference between the outputs of the adjacent carriers. This frequency difference should correspond to a desired carrier spacing between each of the plurality of carriers. A frequency error between the beat frequency and the desired carrier spacing is then measured by down-converting the beat frequency with respect to a target reference frequency corresponding to the desired carrier frequency spacing. Based on the determined frequency error, the optical sources are controlled to adjust in frequency to minimize or reduce the frequency error to zero. For every pair of adjacent carriers, the corresponding outputs of the optical sources are compared in the above manner to determine a plurality of frequency errors. Each optical source can thus be tuned in order to realize a precise carrier spacing between each of the adjacent carriers.
    • 与本公开一致,数字形式的数据由光通信系统的发射节点接收,然后被提供给调制器,调制器进而调制从光源以多个 周期性和优选地最小间隔的波长。 多个周期性间隔的波长或载波以最小载波间隔分组在一起以形成超频道。 通过检测包括两个相邻光源的输出的组合光信号的拍频来确定相邻载波之间的载波间隔。 节拍频率对应于相邻载波的输出之间的频率差。 该频率差应对应于多个载波中的每一个之间的期望载波间隔。 然后通过相对于对应于所需载波频率间隔的目标参考频率下变频拍频来测量拍频和所需载波间隔之间的频率误差。 基于确定的频率误差,控制光源的频率以使频率误差最小化或将频率误差降低到零。 对于每对相邻载波,以上述方式比较光源的相应输出以确定多个频率误差。 因此,可以调整每个光源以便在每个相邻载体之间实现精确的载波间隔。

    • Consistent with the present disclosure, data, in digital form, is received by a transmit nodes of an optical communication, and converted to analog signal by a digital-to-analog converter (DAC) to drive a modulator. The modulator, in turn, modulates light at one of a plurality of wavelengths in accordance with the received data. The modulated light is then transmitted over an optical communication path to a receive node. At the receive node, the modulated optical signal, as well as other modulated optical signals are supplied to a photodetector circuit, which receives additional light at one of the optical signal wavelengths from a local oscillator laser. An analog-to-digital converter (ADC) is provided in the receive node to convert the electrical signals output from the photodetector into digital form. The output from the ADC is then filtered in the electrical domain, such that optical demultiplexing of individual channels is unnecessary.

    • A system receives four-bit symbols that correspond to traffic associated with a three-bit phase modulation scheme and are encoded based on a four-bit phase modulation scheme. The system determines values with which to perform equalization that enable the four-bit symbols to be restored to a condition that existed prior to being transmitted to the system. The system performs, using the values, equalization on a four-bit symbol that includes at least a first pair of bits associated with a first polarization, and performs, after completing the equalization, another equalization on another four-bit symbol that includes at least a second pair of bits associated with a second polarization. The system identifies a three-bit symbol, of a set of three-bit symbols associated with the three-bit phase modulation scheme, based on the equalized first pair of bits and the equalized second pair of bits, generates the three-bit symbol, and outputs the three-bit symbol.

    • Eyewear which preferentially transmits light from a liquid crystal display screen using spectral filtering, polarization filtering and/or spatial filtering. The eyewear transmits the relatively narrow red, green, and blue bands of light emitted by the display's fluorescent backlight lamp, while blocking ambient light falling outside of those relatively narrow bands of light. The eyewear can further include polarized lenses oriented at either + or −45 degrees, matching the polarization of the liquid crystal display emission, and thus blocking ambient light not matching that polarization orientation. The glasses can also be tinted except for a central portion matching the shape of the rectangular liquid crystal display screen, and thus preferentially blocking light not originating from the liquid crystal display screen.
