Integrated Photonics Research in China
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.

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.
by Robert Greenler and David K. LynchThe 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.

Optics Shine in Wuhan, China
China, the second largest economy in the world, is placing a growing emphasis on the development of science and technology. But behind its booming growth, the country is still rooted in the traditional values of family, respect for the elderly, and education. OSA Fellow Barry Masters describes his recent visit to the city of Wuhan and how the educational system there mixes Chinese traditions with Western infl uences.
Promoting Diversity in Optics: A Column Is Born
OSA Board member Ursula Keller and past president Anthony Johnson are pleased to announce a new space in OPN that will explore how the optics community can broaden its own spectrum.
Managing a Research Group
You worked hard to get your Ph.D.; you went through a few postdoc positions around the world; and now your life’s ambition is fulfilled at last: You get to start or develop your own research group. Are you ready? Sure, you are a seasoned scientist, but how good are you at managing other researchers?
