Photonics Dictionary

optical memory: 1. The direct storage of data as bits in memory using optical systems and properties. The memory makes use of a laser beam that is divided by a beamsplitter and controlled by a modulator and a deflector to transpose bits into a given area of storage in memory. On the other side of the memory plane, a laser and a deflector read the memory, bit by bit, the bits being read by a scanning photodetector. Erasure is accomplished by writing with the beam at a different wavelength. 2. The ability of a part to return to its original dimensions after heating and cooling.
