Towards a picosecond transform-limited nitrogen-vacancy based single photon source?

Yo. Room 408 has a new paper on the arXiv that is here. This is the abstract.

We analyze a nitrogen-vacancy (NV^-) colour centre based single photon source based on cavity Purcell enhancement of the zero phonon line and suppression of other transitions? Optimal performance conditions of the cavity-centre system are analyzed using Master equation and quantum trajectory methods? By coupling the centre strongly to a high-finesse optical cavity [Q ~ O(10^4-10^5), V ~ lambda^3] and using sub-picosecond optical excitation the system has striking performance, including effective lifetime of 70 ps, linewidth of 0.01 nm, near unit single photon emission probability and small [O(10^-5)] multi-photon probability?

Hello from New Mexico?

408 is the sum of eight consecutive primes

As the longest serving member of the 408 team the burden falls upon me to broadcast the sad news that we have spent our final day in Room 408. We will announce soon what is to become of Room 408 online, but for now we simply wish to pause in silent remembrance at the end of a wonderful era. Thanks to James, Ivona, Kristian, Simon, Ranjan, Mel, Zac, and Chun-Hsu.
