Capasso lab demonstrates highly unidirectional 'whispering gallery' microlasers
Date:12/13/2010

ies to suitably deform the disks to solve this problem have yielded disappointing results," Capasso added.

By shaping the microlaser as an ellipse with a wavelength-size notch carved out from its edge, Capasso's team found that the cycling whispering gallery modes scatter efficiently off the notch and emerge as nearly parallel beams from the microlaser.

The prototypes are quantum cascade lasers emitting an optical power of 5 milliwatts at a wavelength of 10 microns. The microlaser performance is insensitive to the details of the notch, making this device design very robust.

"Our calculations show that the notched elliptical microlaser should have even better performance at the shorter wavelengths near 1 micron, typical of laser diodes used in optical communications, where the attenuation of whispering gallery modes is negligible," said coauthor Jan Wiersig of the Institute of Theoretical Physics of the University of Magdeburg.

"The successful realization of these simple-structured and robust microlasers through standard wafer-based fabrication makes small-volume directional light sources possible for many important applications such as photonic integrated circuits with high-density chip-scale integration, optical communications, medical/biological sensors, and lab-on-a-chip," said coauthor Masamichi Yamanishi, Research Fellow of Central Research Laboratories at Hamamatsu.
