We report on a hybrid InP/Si photonic crystal nanobeam laser emitting at 1578nm with a low threshold power of ~14.7uW. Laser gain is provided from a single InAsP quantum well embedded in a 155nm InP layer bonded on a standard silicon-on-insulator wafer. This miniaturized nanolaser, with an extremely small modal volume of 0.375(lambda/n)^3 is a promising and efficient light source for silicon photonics.
