An optical memory cell that has four distinctive states, therefore storing 2 bits of information optically, is demonstrated by utilizing a novel single semiconductor microring laser with a retro-reflector cavity. To our best knowledge, it is the first time the combination of two directional and two wavelength states with a single semiconductor ring laser of only 20 times 62 mum2 in size has been demonstrated in which room-temperature continuous-wave operation is realized. These states can be… CONTINUE READING
