摘要： A method and apparatus for matching different impedance of optical components and a package for optical communication using a tapered transmission line (or a taper) are provided. The taper may be configured to include a first section, a second section, and a third section, each of which corresponds to different components. By way of example, the first section of the taper may be configured to be allocated to a driver to a flex joint on a printed circuit board (PCB), the second section of the taper may be configured to be allocated to a flex circuit, and the third section of the taper may be configured to be allocated to a transistor outline (TO) and submount including a directly modulated laser (DML). The taper is configured to minimize an amount of impedance mismatch between the optical components and the package.

摘要： Methods and apparatuses for optical communications are provided. By way of example, an optical transceiver includes a processing device coupled to a memory, an optical subassembly, and a programmable device. The optical subassembly is configured to receive and modulate a first signal carrying high speed user data for transmission to a remote device over an optical link. The programmable device is coupled to the processing device and configured to receive data relating to digital diagnostic monitoring information (DDMI) of the optical transceiver from the processing device, perform forward error correction encoding on the DDMI data to produce a remote digital diagnostic monitoring (RDDM) signal, and send the RDDM signal to the optical subassembly as a second signal to modulate for transmission. The optical subassembly is configured to current modulate the second signal on the first signal to produce a double modulated optical signal for transmission to the remote device.

摘要： Systems and apparatus for data communications comprising a plurality of wavelength tunable submodules in an array is provided. Each submodule has a wavelength tunable laser, and each submodule comprises, as an individual unit, a self-contained wavelength locker having optical and/or optoelectronic functions. The system may be a transponder array comprising a plurality of WDM or DWDM modules. In some embodiments, the individual submodules may comprise photonic integrated wavelength tunable lasers with other optical, electrical and optoelectronic components. Each wavelength tunable submodule incorporated into the module or array can have the same or different optical wavelength and other parameters including but not limited to modulation format. By utilizing the wavelength tunable laser submodules to build a module or array, the need for individual modules dedicated to wavelength sub-bands in the array is eliminated. The same tunable module can be used to fill all the wavelengths on a transmission fiber.
