Paper Abstract

We fabricated and characterized photonic crystal (PhC) microcavities containing InAs quantum dots (QDs) grown on (100) GaAs substrates. QD emission coupled with a PhC cavity mode at a wavelength of 1.55 μm was observed at room temperature. The cavity quality factor Q and its ratio to the mode volume V, Q/V, reach up to 2700 and 3400 x (n/λ)3, respectively. To our knowledge, these are the highest values for microcavities containing QDs emitting at wavelengths around 1.5 μm. The large enhancement of emission intensity at the cavity resonances was clearly observed. The enhancement factor is ~10-100, which depends on cavity modes and pump power density.
