These technologies include low-noise, high-speed, low-power and radiation hardened readout integrated circuit (ROIC) electronics; superconducting sensors; spectral detectors; polarization-sensitive detectors; radiation-hardened detectors; and micro-Kelvin and sub-Kelvin high sensitivity detectors that cover the spectrum from submillimeter wave (Far-IR) to X-ray.","exampleTechnologies":"Backshort Undergrid bolometer arrays, Mercury Cadmium Telluride and Strained Superlattice Arrays, charge coupled devices, sidecar readout integrated circuits, radiometric calibration and abnormality correction algorithms (e.g. non-uniformity)","hasChildren":false,"hasInteriorContent":true}],"startTrl":3,"currentTrl":5,"endTrl":5,"benefits":"Far-infrared astronomical instruments on board SPICA, a japanese-led, JAXA-ESA joint mission scheduled to launch in 2017.

These features are key in design and optimization of the multi-layered structure of BIBs, and their implementation and quality are crucial in optimum operation of these detectors. The proposed process is a drastic departure from conventional epitaxial methods, such as chemical vapor deposition and liquid phase epitaxy, which have yet to produce far IR BIBs suitable for astronomical instruments. Germanium BIBs will offer extended wavelength response up to at least 200µm, high quantum efficiency, high immunity to ionizing radiation, and elimination of long-term transient and memory effects. Coupled with their compatibility with Si cryo-CMOS readout multiplexers and the planar, bump-bond hybridization process, these detectors will make possible the construction of large format, high sensitivity FPAs for far IR astronomy and will replace the current unstressed and stressed germanium detectors.","startYear":2011,"startMonth":6,"endYear":2013,"endMonth":11,"statusDescription":"Completed","principalInvestigators":[{"contactId":191474,"canUserEdit":false,"firstName":"Jam","lastName":"Farhoomand","fullName":"Jam Farhoomand","fullNameInverted":"Farhoomand, Jam","publicEmail":true,"nacontact":false}],"programDirectors":[{"contactId":206378,"canUserEdit":false,"firstName":"Jason","lastName":"Kessler","fullName":"Jason L Kessler","fullNameInverted":"Kessler, Jason L","middleInitial":"L","primaryEmail":"jason.l.kessler@nasa.gov","publicEmail":true,"nacontact":false}],"programExecutives":[{"contactId":215154,"canUserEdit":false,"firstName":"Jennifer","lastName":"Gustetic","fullName":"Jennifer L Gustetic","fullNameInverted":"Gustetic, Jennifer L","middleInitial":"L","primaryEmail":"jennifer.l.gustetic@nasa.gov","publicEmail":true,"nacontact":false}],"programManagers":[{"contactId":62051,"canUserEdit":false,"firstName":"Carlos","lastName":"Torrez","fullName":"Carlos Torrez","fullNameInverted":"Torrez, Carlos","primaryEmail":"carlos.torrez@nasa.gov","publicEmail":true,"nacontact":false}],"projectManagers":[{"contactId":3163995,"canUserEdit":false,"firstName":"Robert","lastName":"Jones","fullName":"Robert Jones","fullNameInverted":"Jones, Robert","primaryEmail":"Robert.A.Jones@nasa.gov","publicEmail":true,"nacontact":false},{"contactId":461333,"canUserEdit":false,"firstName":"Theresa","lastName":"Stanley","fullName":"Theresa M Stanley","fullNameInverted":"Stanley, Theresa M","middleInitial":"M","primaryEmail":"theresa.m.stanley@nasa.gov","publicEmail":true,"nacontact":false}],"website":"","libraryItems":[],"transitions":[{"transitionId":65924,"projectId":9848,"partner":"Other","transitionDate":"2011-06-01","path":"Advanced From","relatedProjectId":8659,"relatedProject":{"acronym":"","projectId":8659,"title":"An Implant-Passivated Blocked Impurity Band Germanium Detector for the Far Infrared","startTrl":2,"currentTrl":3,"endTrl":3,"benefits":"Far-infrared astronomical instruments on board SPICA, a japanese-led, JAXA-ESA joint mission scheduled to launch in 2017.

The NASA SBIR and STTR programs fund the research, development, and demonstration of innovative technologies that fulfill NASA needs as described in the annual Solicitations and have significant potential for successful commercialization. If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
