We have observed light emission at a wavelength of 1.55 mu m from InAs quantum dots (QDs) embedded in a high-quality-factor photonic crystal (PhC inicrocavity for the first time. The InAs QDs were grown on a (100) GaAs substrate and the photoluminescence measurement was performed at room temperature. The cavity quality factor Q reaches 2700, which is close to the resolution limit of our measurement system. Due to the small mode volume V of the PhC cavity, Q/V increases up to 3400 x (n/lambda)(3). These are the highest values ever reported for microcavities containing QDs emitting in a spectral range around 1.5 mu m. Details of the optical properties of the microcavity, such as polarization and pump power density dependences are also discussed.
