IR Spectrometers

2.0K
There are two main infrared (IR) spectrophotometers: dispersive IR spectrometers and Fourier transform infrared (FTIR) spectrometers. In a dispersive IR spectrometer, a beam of infrared radiation produced by a hot wire is divided into two parallel equal-intensity beams using mirrors. One beam passes through the sample, while another is a reference beam. The beams then move through the monochromator, which separates the radiations into a continuous spectrum of different frequencies. The...

    Area of Science:

    • Optics and Photonics
    • Materials Science
    • Semiconductor Devices

    Background:

    • Thermal noise in mid-wave and long-wave infrared (MWIR and LWIR) cameras and focal plane arrays (FPAs) is a significant challenge.
    • Reducing photodetector area can decrease thermal noise but requires efficient photon collection.
    • Light-concentrating structures offer a potential solution by enhancing photon capture on smaller detector areas.

    Purpose of the Study:

    • To investigate the use of microconical silicon (Si) light concentrators for reducing thermal noise in MWIR/LWIR FPAs.
    • To explore methods for integrating Si microcones with FPAs to improve photon collection and operating temperatures.
    • To analyze the performance of different microcone designs and integration strategies.

    Main Methods:

    • Numerical modeling in the mesoscale regime to design microconical Si light concentrators with (111) oriented sidewalls.
    • Fabrication of microcones using anisotropic wet etching of Si (100) wafers.
    • Study of three integration methods: inverted microcones with heterogeneous integration, inverted microcones with monolithic integration (Schottky barrier detectors), and regular microcones with monolithic integration.

    Main Results:

    • Inverted microcones with heterogeneous integration achieved resonant power enhancement factors (PEF) up to 10 and angles-of-view (AOV) up to 10°.
    • Monolithic integration of inverted microcones with Schottky barrier photodetectors yielded resonant PEFs up to 25 and AOVs up to 30° for both polarizations.
    • Regular microcones provided non-resonant power concentration with large AOVs, functioning similarly to optical components like dielectric microspheres.

    Conclusions:

    • Silicon microcone light concentrators are a viable solution for reducing thermal noise in infrared FPAs.
    • Inverted microcone designs enable multispectral imaging with narrow bands (∼100 nm) and large AOVs.
    • The proposed integration methods offer pathways to enhance FPA performance, including increased operating temperatures and improved imaging capabilities.
