Improving the Performance of Sampled-Grating DBR Laser-Based Analog Optical Transmitters

Leif A. Johansson;Yuliya A. Akulova;Chris Coldren;Larry A. Coldren

Journal of Lightwave Technology
Year: 2008 | Volume: 26, Issue: 7 | Journal Article |

In this paper, the available analog link performance of integrated transmitters containing a sampled-grating distributed Bragg reflector laser, a semiconductor optical amplifier, and a modulator is evaluated. It is found that to provide a link gain and a low-noise figure, an RF preamplifier is required, and for this reason, spurious-free dynamic range (SFDR) including a preamplifier has been evalu...Show More

Vertical cavity surface-emitting lasers (VCSELs) are becoming increasingly important for short-haul optical fiber transmission systems. Given the commercial success of GaAs-based 850 nm VCSELs, dramatic enhancements in transmission bandwidth and distance can be achieved in conventional single- and multi-mode fiber by extending the emission wavelength to the 1300 nm-1550 nm range. GaInNAs is a prom...Show More

Group III-nitride-arsenides were grown by MBE employing a nitrogen radio frequency (rf) plasma. To improve the luminescence efficiency, both GaNAs and GaInNAs must be annealed, this anneal improves the crystal quality but also causes nitrogen outdiffusion. Broad area lasers and vertical cavity surface emitting lasers (VCSELs) have been fabricated.Show More

Nitride-arsenides are promising materials for long wavelength opto-electronic devices grown on GaAs substrates. The photoluminescence intensity of GaNAs and GaInNAs quantum wells increases drastically and shifts to shorter wavelengths following high temperature anneal. A study of PL after different annealing conditions revealed that the wavelength shift and the intensity increase occur together. W...Show More
