Description

This is a modification to the synopsis entitled "Broad-Band Pyroelectric IR Detector for FIRST (FAR-Infared Spectroscopy of the Troposphere)Reference Number: RFJ.1186 which was posted on June 28, 2001. You are hereby notified that a detailed Statement of Work is provided as follows: NASA Langley Research Center (LaRC) requires sensitive far-infrared detectors for use in a Fourier transform spectrometer (FTS). To meet the requirements of future space missions the detectors must demonstrate the required sensitivity and electronic bandwidth at ambient temperature or at temperatures that can be reached with passive cooling in space (~180 K). The Contractor shall design, fabricate and characterize a prototype detector. The contractor shall design an on-chip preamplifier, fabricate integrated detector/preamp, characterize and deliver detector system. Detector characterization includes measurements of responsivity, specific detectivity, and noise as functions of modulation frequency and wavelength. The minimum range in frequency is 10-3000 Hz. The desired test range for wavelength is 5-100 mm, and the minimum range is 5-20 mm. Detector Specifications: 1. Detectivity: Goal is 1.8x1010 cm Hz0.5 W-1, minimum is 1010 cm Hz0.5 W-1. Operating temperature: 180-300 K; vendor may specify an optimum operating temperature within this range. 2. Optical band: Detectivity must equal or exceed the minimum requirement 10-50 mm wavelength range minimum. NASA Langley plans to award to Southern Methodist University on a sole source basis since SMU has developed an approach to fabricate pyroelectric detectors with sensitivity that approaches the thermal noise limit at room temperature.
