Magneto-optic materials and devices, including arrays, have been in development since the 1980’s. Active-matrix TFT addressing was commercialized in the 1990’s, as an extension of the robust materials and array development programs of bubble-memory programs utilizing MO arrays. Interconnect and metallurgy were well developed by the end of that decade.
In addition, cost-effective, high-quality MO films were at a high state of commercial availability due to the longstanding commercial application of MO devices (isolators and rotators) in telecom, sensing, bubble-memory development, and recordable optical discs. However, very serious obstacles to a practical MO display and a high-performance SLM up until the early 2000’s included limitations on array size, very large magnetic (B) fields, magnetic cross-talk, insufficient domain penetration, optical cross-talk, power requirements for pixel switching, lack of color capability, and manufacturing cost.
