[转帖]India launches photonics push

BANGALORE, India — The Department of Information Technology has launched several programs to develop an indigenous photonics capability.

The initiative covers systems, devices and materials, with research being conducted at several Indian research and educational institutes in order to hasten development.

A national facility will be created for packaging photonic devices at the Society for Applied Microwave Electronic Engineering and Research in Mumbai. An auto-alignment system to align fibers with devices for maximum coupling of light will also be established at the Mumbai facility.

Passive photonic devices such as planar light circuits built on a variety of substrates will benefit from the packaging work. Trial packaging runs have been carried out on power splitters, and companies are now evaluating the splitters.

A laser weld system needed for active device packaging is being set up here, according to the IT ministry.

Elsewhere, a national institute at Pilani in northern India has developed laser diode chips while efforts are underway at the Indian Institute of Technology in New Delhi to develop an optical amplifier system.

A preliminary study is also underway at an institute here on photonic devices using polymer as a sandwich layer between fixed and flexible electrodes.
