- Abstract
- The 1.3-mum uncooled InGaAsP-InP loss-coupled distributed feedback lasers operating over 10 Gb/s and at 85 degreesC were successfully fabricated. In order to achieve their high-speed and high-temperature operations simultaneously, the following are thoroughly investigated: modulation-doped and strain-compensated multiple-quantum-well active layers, Fe-doped buried-heterostructure, coupling coefficient of loss-coupled grating, detuning lasing wavelength from the gain peak, and facet coatings. The authors also demonstrate 10 Gb/s transmission with negligible dispersion power penalty over 20 km of nondispersion-shifted fiber at 10 Gb/s for the temperature ranging from 25 degreesC to 85 degreesC.
