Abstract: A WDM device having a controller that individually controls the operating parameters of tunable lasers and the temperatures of an optical multiplexer and etalon. The device employs a spectral analyzer to measure the spectral composition of the optical output signal produced by the device. Based on the analyses of the measured spectral composition, the controller sets the temperatures of the tunable lasers, optical multiplexer, and optical etalon to values that cause: (i) middle frequencies of transmission bands of the optical multiplexer to be spectrally aligned with the corresponding frequencies of the specified frequency grid, (ii) each laser line to be properly positioned within the corresponding transmission band, and (iii) transmission resonances of the optical etalon to be properly positioned with respect to the laser lines.

Abstract: An optical transmitter that uses half-rate electrical signals, without multiplexing them to the full rate, to generate a full-rate optical duobinary signal. In one embodiment, an optical transmitter of the invention has a Mach-Zehnder modulator (MZM) driven by two half-rate electrical data streams. A first half-rate data stream is applied to drive a first arm of the MZM. A delay element misaligns a second half-rate data stream that is synchronized with the first data stream by one half of a bit period, and the resulting misaligned data stream is applied to drive a second arm of the MZM. The MZM is configured to (i) transmit substantially no light from the feeding laser when the applied data streams have the same binary value and (ii) have a maximum transmission when the applied data streams have different binary values, thereby generating a full-rate optical duobinary signal at its output.

Abstract: A dispersion compensator having relatively uniform transmission characteristics over the bandwidth of a communication channel. The compensator is designed to process an optical signal corresponding to the communication channel by decomposing that signal into spectral components, routing different components along different optical paths that impart relative delays between the components, and recombining the delayed components spatially and directionally to generate a processed optical signal with reduced chromatic dispersion. In one embodiment, the compensator is a waveguide circuit that includes four diffraction gratings operating in transmission and optically coupled to a tunable lens array, in which different tunable lenses receive light corresponding to different communication channels. For each channel, a desired group delay value is produced by selecting magnification strength of the corresponding tunable lens.

Abstract: An optical assembly for a wavelength-division-multiplexing (WDM) transmitter or receiver that lends itself to cost-effective production-line manufacturing. In one embodiment, the fiber optic assembly has a vernier-type arrayed waveguide grating (AWG) with five optical ports at one side and fourteen optical ports at another side. Ten of the fourteen ports are optically coupled to ten photo-detectors or lasers. A selected one of the five ports is optically coupled to an external optical fiber. The coupling optics and the mounting hardware for the AWG are designed to accommodate, with few relatively straightforward adjustments performed on the production line, any configuration of the AWG in which any consecutive ten of the fourteen ports are optically coupled to the ten photo-detectors or lasers.
