Photonics Spectra: November 2015

Optimization of a Coherent OMA Acquisition System
The demand for optical network data has soared, with rates of 100 Gb/s evolving into 400 Gb/s, 1 Tb/s and beyond, pushing designers to explore inventive and even unconventional modulation schemes in order to encode data more efficiently for faster throughput. In this context, it can pay off for designers to think about how to optimize their testing environment to quickly and accurately evaluate...

Imaging, Optics … and Beyond!
Less than a decade ago, scientists could see Mars, but with very little detail beyond the surface. Thanks to some advanced technology on board NASA’s Curiosity rover, which touched down on the Red Planet in 2012, and the Mars Reconnaissance Orbiter (MRO), which has been examining Mars since 2006, we can now see detailed images of rough terrain and even evidence of intermittently flowing...
