128x128 Ultra-High Density Optical Interconnect, Phase I

Future NASA programs like Tertiary Planet Finder (TPF) require high density deformable mirrors with upto 16,000 actuators to enable direct imaging of planets around distant stars. Xinetics has been developing high density module actuator arrays that will enable deformable mirrors to be fabricated with array sizes upto 128 by 128. These monolithic actuator arrays have eliminated the need for descrete wires by using internal electrical conductors that teminate at the back of the module. Concepts for electrical attachment using Ball Grid Arrays (BGA), Pin Grid Arrays (PGA) and conductive epoxies have been developed to allow laboratory testing and evaluation, but reliable interconnect technology must be developed that will allow the module mirror technology to meet space qualification requirements. Environmental requirements for the interconnect include radiation, mechanical, thermal and life cycle loads. The interconnect must also survive subsequent assembly processes including thermal and coating vacuum cycles. We are proposing under Phase I to investigate electrical interface options, materials and processes for the module arrays compatible with future space qualificaiton requirements. During a follow on Phase II a high density interconnect for a full scale 128 by 128 mirror would be built and assembly processes qualified with rigous testing.

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
