چکیده
We present continuous wave laser emission in a photonic crystal microcavity operating at 1.5 microm at room temperature. The structures have been fabricated in an InP slab including a single layer of self-assembled InAs/InP quantum wires (QWrs) as active material. Laser emission in air suspended membranes with thresholds of effective optical pump power of 22 microW and quality factors up to 55000 have been measured.

Emission wavelength engineering of InAs/InP(001) quantum wires
In this work we have studied the dependence of the optical properties of self-assembled InAs quantum wires (QWr) grown on InP(001) on the growth temperature of the InP cap layer, as a mean for controlling the InAs QWr size. Our main result is that we can tune the emission wavelength of InAs QWr either at 1.3 μm or 1.55 μm at room temperature. We suggest that the role of growth temperature is to...

We report a single layer InAs/InP (100) quantum dot (QD) laser operating in continuous wave mode at room temperature on the QD ground state transition grown by metal organic vapor phase epitaxy. The necessary high QD density is achieved by growing the QDs on a thin InAs quantum well (QW). This QDs on QW laser exhibits a high slope efficiency and a lasing wavelength of 1.74 μm. An extremely long...
متن کاملPurcell effect in photonic crystal microcavities embedding InAs/InP quantum wires.
The spontaneous emission rate and Purcell factor of self-assembled quantum wires embedded in photonic crystal micro-cavities are measured at 80 K by using micro-photoluminescence, under transient and steady state excitation conditions. The Purcell factors fall in the range 1.1 - 2 despite the theoretical prediction of ≈15.5 for the figure of merit. We explain this difference by introducing a po...
