Planar Waveguide Battleground

Facebook X LinkedIn Email
Echelle gratings compete with arrayed waveguide gratings for complex, high-channel-count optical integrated circuit applications.

Dr. Sylvain Charbonneau and Dr. Matthew Pearson

The demand for increased communications bandwidth in North America is rapidly being replaced by demands for technology that will allow service providers to use existing optical capacity more efficiently and profitably. Consequently, a growing number of component manufacturers are focusing resources on developing cost-effective solutions for multiplexing and demultiplexing wavelengths. Many of these companies are turning to planar waveguide devices to deliver complex optical integrated circuits that offer increased scalability and superior performance at a lower cost. As optical networks...Read full article
