Since the invention of the laser in 1960 and semiconductor lasers in 1962, the size of lasers has been reduced significantly. In this talk, we discuss electrical-injection semiconductor nanolasers and nano-light emitting diodes (LEDs) using a metal-cavity surface-emitting structure flip-chip bonded to a silicon substrate. We use bulk, quantum wells, and quantum dots in the active region of the nano-lasers. Our strategy toward sub-wavelength nanscale lasers is presented with experimental results at room temperature. Theoretical analysis is also shown with an excellent agreement with the experimental data. Such lasers might present an important breakthrough toward future on-chip optical communication of integrated circuits (ICs).
