Ultra-low Threshold Lasers

The increasing use of semiconductor lasers (SCLs) as optoelectronic components has led to recent efforts to substantially lower the threshold current of these lasers. In addition, future computer interconnect circuitry (board-to-board, chip-to-chip) envisages the use of very large numbers of such lasers, on-chip, so that a major reduction of their power requirement is of prime importance.
