Enhanced spontaneous emission from InAs GaAs quantum dots in pillar microcavities emitting at telecom wavelengths

Not Accessible

Your library or personal account may give you access

Abstract

Optical properties of InAsGaAs quantum dots in micropillar cavities emitting at 1.3μm are studied by time-resolved microphotoluminescence. The Purcell effect is observed with an enhancement of the decay rate by a factor of two for quantum dots in resonance with the cavity mode.
