Single photon emission fromgallium nitride quantum dots atarecord-short wavelength of357nm

Wepresent measurements ofthesecond-order coherence fmnction onemission from single GaNquantum dots. A large degree ofphoton antibunching isobserved, demonstrating single-photon source operating atarecord-short wavelength of357nm. ©2005 Optical Society ofAmerica OCIScode: (300.6470) Spectroscopy, semiconductor; (270.5290) Photon statistics
