Abstract

The first continuous-wave (CW) operation of 2D slab photonic crystal laser at room temperature is presented. The laser cavities are optically pumped normal to the structure using a 980-nm InGaAs laser focused to a spot size of approximately 10 μm. A typical room temperature continuous wave lasing spectrum is discussed. The cavity has 21 un-drilled holes along the diagonal direction. The lasing wavelength is 1604 nm with linewidth of approximately 0.35 nm. The lasing wavelength red-shifts at a rate of 1.2 nm/mW. For smaller cavities, lasing is maintained up to approximately 30% of duty cycle but CW operation has not reached.
