Abstract:

We report on the generation of single-photon pulses from a single InAsInP quantum dot in telecommunication bands 1.3-1.55 micrometers higher transmittance through an optical fiber. First we prepared InAs quantum dots on InP 0 0 1 substrates in a low-pressure MOCVD by using a so-called InP double-cap procedure. The quantum dots have well-controlled photo emission wavelength in the telecommunication bands. We also developed a single-photon emitter in which quantum dots were embedded. Numerical simulation designed the emitter to realize efficient injection of the emitted photons into a single-mode optical fiber. Using a Hanbury-Brown and Twiss technique has proved that the photons through the fiber were single photons.
