Chinese researchers already have a decades-long history of making key contributions to integrated photonics research. Now, with a growing number of research groups and unprecedented government backing, the country is poised to take a leading role in this exciting area, which is a critical driver of global communications technology.


Light and Color in Nature: A Return to Optics’ Roots

Past OSA President Bob Greenler and OSA Fellow Dave Lynch describe a remarkable conference series in which scientists gather to explore beautiful naked-eye phenomena in the world around us.

The Green Laser Diode: Completing the Rainbow

Traditionally, green laser diodes have been difficult to construct due to the characteristics of the quantum wells that serve as their gain region. Now, however, several companies and research groups have found ways to fill this “green gap,” by mastering the epitaxy of high-indium-containing quantum wells, balancing strain and defect formation against the quantum-confined Stark effect and using optimized waveguides. Their work is driving new applications in consumer electronics, biophotonics and other areas.
