—A widely tuneable electroabsorption-modulated sampled-grating distributed Bragg reflector laser, integrated with a semiconductor optical amplifier is characterized for analog applications. The wavelength can be tuned anywhere from 1522 to 1573 nm. The suboctave spurious-free dynamic range (SFDR) is between 125–127 dBHz 4 5 measured at eight sampled… (More)
Integration of active optical components typically serves five goals: enhanced performance, smaller size, lower power dissipation, higher reliability, and lower cost. We can differentiate between horizontal and vertical integration schemes. Horizontal integration combines many elements of the same functionality, like laser arrays. Vertical integration… (More)
—Sampled-grating distributed Bragg grating (SGDBR) laser-based widely tunable optical transmitters are investigated for application in high-performance analog links. More than 45 nm tuning range, 40 dB sidemode suppression ratio, and peak relative intensity noise below 153 dB/Hz is measured. SGDBR lasers integrated with semiconductor optical amplifiers and… (More)
We report on a sampled grating DBR laser monolithically integrated with an electroabsorption modulator and semiconductor optical amplifier. A fiber coupled time-averaged power in excess of 3 dBm across a 40 nm tuning range and 2.5 Gb/s transmission over 200 km of standard fiber are achieved.
Generation and transmission of 10 Gbps duobinary signals is demonstrated using an integrated widely-tunable SGDBR laser and Mach-Zehnder modulator over a wavelength range of 1538nm – 1564nm. 1. Introduction Duobinary modulation has the advantage of more compact modulated optical spectral width compared to standard NRZ modulation . This provides improved… (More)
Today, a wide variety of probabilistic and expert AI systems are used to analyze real world inputs such as unstructured text, sounds, images, and statistical data. However, all these systems exist on different platforms, with different implementations, and with distinctly different, often and very specific goals in mind. This paper introduces a concept for… (More)
