Semiconductors Deposited in Fiber Preforms

Facebook X LinkedIn Email
Researchers at Syracuse University have developed a technique that could lead to the production of more efficient optical fiber devices. They employed optical deposition to create fiber preforms with a semiconductor layer at the core-cladding boundary. Graduate student Nitipun Navatrong filled glass ampoules with a borosilicate glass rod and either GaSb, Cd3P2 or CdTe. He illuminated them with a 1000-W halogen lamp, which caused the semiconductor material to coat the rods. The ampoules were subsequently collapsed without exposing the semiconductor layer to air.
