Extremely uniform angular distributions of the three-dimensional emission spectra of photonic quantum ring lasers

We have observed the emission spectra of three-dimensional Rayleigh-Fabry-Perot cavity whispering-gallery modes from photonic quantum ring lasers that give rise to uniform angular mode spacing in space. The observed angular distribution (0 degrees approximately 30 degrees) of the emission modes is l...

Summary:We have observed the emission spectra of three-dimensional Rayleigh-Fabry-Perot cavity whispering-gallery modes from photonic quantum ring lasers that give rise to uniform angular mode spacing in space. The observed angular distribution (0 degrees approximately 30 degrees) of the emission modes is linear with respect to the mode number. For example, the average angular mode spacing is 0.95 degrees with a standard deviation of 0.098 degrees for a 20-microm-diameter laser, whose potential angle-resolving power is promising for angle-sensing applications in the future.
