Abstract :

How small a laser can be practically realized? – it is not a curiosity question any more in view of perceived future

requirements of all-optical signal processing in communications, quantum computing. This is the question asked

at the forefront of the photonics research. In this talk, the search for the smallest possible laser over the last three

decades will be reviewed. The evolution of resonant cavities from the 1-D vertical cavity surface emitting laser

to the 2-D photonic crystal laser and back to the 1-D ladder-type nano-beam laser will be discussed with biased

historical perspectives. Detailed emphases will be placed on recent 1-D nanobeam lasers.
