Room-temperature electrically pumped nanolaser is designed for photonic integrated circuits
An electrically pumped ring-shaped surface plasmon-polariton nanolaser double heterostructure consists of an InAsP/InGaAs/AlInAs layer stack on AlInAs surrounded by silicon oxide and a gold superstrate. (Image credit: Dmitry Fedyanin) Of all the components in a photonic integrated circuit, the laser light source is the most problematic; because silicon itself does not easily emit light, other […]
