Abstract:
We report on InP-based p-type/intrinsic/n-type (PIN) photodiodes with a novel strain-compensated type-II InGaAs/GaAsSb quantum well active region. The device has optical response out to 3.0 μm, specific detectivity (D*) of 7.73×10(9) cm Hz(0.5)/W at 290 K for 2.7 μm. These preliminary results show that this novel strain-compensated approach leads to similar performance when compared to a conventional strain-compensated approach.
