摘要： A multi-stage tunable gain optical amplifier device amplifies an optical signal by a gain amount which can be adjusted in one of the stages of the amplifier. The multi-stage amplifier includes at least two optical amplifier stages coupled in series, one of which is a tunable gain amplifier stage. The optical amplifier stages are characterized by a design parameter which varies from stage to stage. In a preferred embodiment, the design parameter includes a noise figure and a saturable power, with both parameters increasing as the optical signal propagates from stage to stage. As a result, the multi-stage tunable gain optical amplifier can achieve better noise performance and higher output power than a single stage optical amplifier with a constant noise figure and saturable power.

摘要： An optical signal power monitoring and control system is described. The system comprises at least one lasing SOA that receives, amplifies, and outputs the optical signal. In response to the signal amplification, a ballast laser signal is output through a substrate of the lasing SOA. This ballast laser signal is indicative of the optical signal power. At least one detector converts the ballast laser signal to an electrical signal and transmits this electrical signal to a power monitor circuit. Using the electrical signal, the power monitor signal may determine the power of the electrical signal and the gain across the lasing SOA. A gain control circuit may adjust the gain across a tunable-gain lasing SOA or multi-stage optical amplifier in order to optimize the optical signal's strength. The electrical signal power and lasing SOA gain may be transmitted to a terminal to display this information or a warning may be generated when certain criteria are met.

摘要： Optical systems and devices are provided that include or facilitate the ability to provide early detection of the failure of an optical transmitter such as a laser. Such detection may be made with reference to various aspects of the operation and performance of the optical transmitter. For example, some of the optical systems and devices employ wavelength shift information to make determinations concerning potential failure of an optical transmitter. Other optical systems and devices use information concerning the efficiency with which an incoming pump current is converted into the ballast laser signal changes to make determinations concerning potential failure of an optical transmitter.
