摘要： In a coarse wavelength division multiplexing (CWDM) optical transmission system, a distributed feedback (DFB) laser is tuned so that the peak reflection of the grating overlaps with the gain range of the DFB laser. The diffraction grating is tuned so that the peak is positioned on the long wavelength end of the gain spectrum at a selected temperature. The optical transmission system operates in an environment having a wide temperature range (i.e., about -40°C to about 85°C). Heat is applied to the laser and as the laser temperature increases, the gain range overtakes the grating peak. When the gain range and the grating peak overlap at increased laser temperature, laser output is improved.

A method of transmitting optical signals generally includes modulating light emitted from a first light source using a first modulator, and modulating light emitted from a second light source using a second modulator, where the first modulator receives a first modulation signal, and the second modulator receives a second modulation signal electrically isolated from the first modulation signal.

The laser may be manufactured by forming a lower semiconductive buffer layer on a substrate, an active layer including one or more quantum well layers having the variable energy bandgap on or above the lower semiconductive buffer layer, an upper semiconductive buffer layer on or above the active layer, a contact layer on or above the upper semiconductive buffer layer, and an isolation region separating the light emission region and the modulation region.

摘要： A method and apparatus is presented for providing improved responsiveness of a receiver device. One embodiment includes a receiver device including an avalanche photodiode (APD), a transimpedance amplifier (TIA), and an automatic gain control (AGC) device configured to adjust the reverse bias voltage applied to the APD according to an approximate DC average of the incoming optical signal. A switch in the AGC device may be used to increase or decrease the time constant of an RC combination determining the DC averaging time period, thereby tailoring the response of the AGC device to characteristics of the incoming data pattern. The resulting receiver exhibits improved responsiveness and sensitivity by adapting to varying data patterns including those with data bursts interspersed with gaps.
