Abstract

The coupling between single 1.3 μm InAs quantum dots (QDs) and photonic crystal nanocavities with quality factors Q up to 15000 is showed. In this condition the Purcell effect (increased spontaneous emission rate) is observed for the first time at these wavelengths. This result is an important step for the development of semiconductor based single photon sources at telecom wavelength, a fundamental need for application like quantum cryptography and quantum computing.
