Abstract
An optical device includes an array of optical elements located over a package substrate. A controller is also located over the package substrate. The controller is operable to control an operational state of the array in response to an optical signal detected by an optical receiver.
Claims20
An optical device, comprising:
- an array of optical elements located over a package substrate;
- and
- a controller located over said package substrate and operable to control an operational state of said array in response to an optical signal detected by an optical receiver.
A method of operating an optical device, comprising:
- providing an array of optical elements located over a substrate;
- electrically coupling at least one optical receiver to a controller operable to control an operational state of said array in response to an optical signal detected by said optical receiver;
- illuminating said optical receiver with illumination light adapted to convey array state data, and
- changing said operational state in response to said data.

A digital projection system, comprising:
- a spatial light modulator, comprising an array of modulation elements located over a package substrate;
- a projection light source configured to illuminate said array with projection light;
- a control-modulated light source configured to illuminate an optical receiver with light control-modulated with data associated with an array state;
- optics configured to project an image produced in response to modulation of said projection light by said array in said state, and
- an array controller located over said package substrate and configured to control said state in response to said data detected by said optical receiver.
