THE OBJECTIVE OF THE PROPOSED WORK WAS TO DEVELOP A MEDIUM-RESOLUTION (R=15000) NEXT-GENERATION NEAR-INFRARED HETERODYNE SPECTROMETER WITH ASSOCIATED ELECTRONICS FOR FUTURE PLANETARY MISSIONS. THE SPECTROMETER DEVELOPMENT WOULD LEVERAGE THREE MORE RECENT ADVANCES IN INTEGRATED PHOTONICS TECHNOLOGY--(A) PHOTONIC LANTERN (PL) TECHNOLOGY FOR ASTRONOMY; (B) ARRAYED WAVEGUIDE GRATINGS (AWGS); AND (C) PHOTONICS INTEGRATED CIRCUITS (PIC) FOR THE TELECOMMUNICATION INDUSTRY. THE PIC ALLOWED INTEGRATION OF ELECTRO-OPTIC COMPONENTS INCLUDING AWGS AND LOCAL OSCILLATORS FOR HETERODYNE DETECTION TO YIELD A COST-EFFECTIVE SMALLER LIGHTER LOWER POWER INSTRUMENT FOR CUBESAT AND SMALLSAT APPLICATIONS AS WELL AS LARGER SATELLITES. THE PROPOSED INSTRUMENT PROTOTYPE WOULD FOCUS ON THE CO SPECTRAL BAND AT 4.6-4.8 UM WHICH IS OF KEY IMPORTANCE TO COMETARY SCIENCE. DURING THE PROPOSED THREE-YEAR PERFORMANCE PERIOD THE TEAM WOULD (I) DEVELOP KEY COMPONENTS AND SUBSYSTEMS; (II) INTEGRATE SUB-SYSTEMS TO BUILD A COMPLETE INSTRUMENT; (III) DEMONSTRATE AND VALIDATE HIGH SENSITIVITY MEASUREMENTS.
