CIP wins $3 million for uncooled laser program

The Center for Integrated Photonics, in partnership with Bookham, Loughborough Surface Analysis, Epichem, and two UK universities, has won $3 million to develop uncooled high-speed lasers and optical amplifiers.

A UK collaboration involving the Centre for Integrated Photonics (CIP), Bookham, Epichem, Loughborough Surface Analysis (LSA), and the universities of Surrey and Sheffield has netted £1.7 million ($3 million) to develop new technologies for uncooled operation of InP-based photonic components.

The funding from the UK's Department of Trade and Industry will be used for a two and a half year project entitled "Extended Temperature Electronics".

The project's first aim is to fabricate a range of aluminum containing active devices that can operate at high temperatures. These devices will include fixed and tunable lasers, semiconductor optical amplifiers (SOAs), superluminescent diodes and avalanche photodiodes.

The project's other goal is to develop MOCVD processes for the growth of ruthenium-doped semi-insulating current blocking layers that could lead to higher modulation speeds for active devices.

According to CIP, the project should lead to high speed, high power lasers and SOAs that can operate without cooling, and should enable reductions in power consumption and allow closer stacking of optical interfaces.

The CIP and Bookham will be responsible for the growth and device testing, and will contribute to the structural design and modeling along with Surrey and Sheffield universities. EpiChem will provide the precursor technology, and LSA and the two universities will carry out material and device characterization.
