摘要： The present invention provides a compact, low cost integrated continuous wave (CW) laser/electro-absorption (EA) modulator solution that supports the non-return to zero (NRZ) modulation format for long-haul optical transmission that results in high output extinction ratio of an integrated EA modulated laser (EML) and low modulator chirp. The methods and systems of the present invention treat the laser and EA modulator sections of the EML as separate components. An information signal is connected to two separate drivers: a laser driver that drives the laser section and a modulator driver that drives the EA modulator section.

摘要： Systems and methods are described for reducing coherence effect in narrow line-width light sources through various modulation techniques. The systems and methods can include a narrow line-width laser source with a thermoelectric cooler thermally coupled thereto and a controller communicatively coupled to the thermoelectric cooler. The controller is configured to provide a varied input signal to the thermoelectric cooler to reduce coherence of the narrow line-width laser source by artificially broadening the narrow line-width on a time averaged basis. The systems and methods can also include direct modulation of the narrow line-width laser source. The systems and methods can include a narrow line-width Optical Time Domain Reflectometer (OTDR). The systems and methods can also include direct modulation of the narrow line-width laser source with or without the varied input signal to the thermoelectric cooler.
