Research on thermal stability of monolithic nearinfrared Doppler asymmetric spatial heterodyne interferometer

Chenguang Chang et al.

Summary: This article presents the design of a DASH interferometer for measuring atmospheric winds at a height of 60 to 80 km. The interferometer exhibits decent thermal stability, and an optical-structural-thermal integrated analysis method is proposed to accurately calculate and optimize thermal drift during the design phase. Experimental and analytical results show good agreement, validating the effectiveness of the analysis method.

Michelson Interferometer for Global High-Resolution Thermospheric Imaging (MIGHTI) On-Orbit Wind Observations: Data Analysis and Instrument Performance

Christoph R. Englert et al.

Summary: This article updates and expands the analysis of wind data from the Michelson Interferometer for Global High-resolution Thermospheric Imaging (MIGHTI) on the NASA Ionospheric Connection (ICON) satellite, and discusses the performance of the instrument in orbit. Key processing steps, including the correction of a signal-intensity dependent phase shift, are described. A new zero-wind calibration approach is preferred over the originally planned approach due to its higher precision. The wind uncertainties are updated and compared to mission requirements, showing that MIGHTI has met the ICON mission requirements. Comparisons with ground-based observations also demonstrate good agreement.

Design of an efficient thulium-doped fiber amplifier for dual-hop earth to satellite optical wireless links

Jawad Mirza et al.

Summary: Optical wireless communication (OWC) links face challenges from atmospheric attenuation and turbulence, especially in deep space links. To improve the link budget and achieve error-free transmission, high-output power and gain optical amplifiers are needed. In this paper, an efficient Thulium-doped fiber amplifier (TDFA) design with dual-stage pumping scheme is proposed for a dual-hop earth to satellite OWC Link. The experimental results show that the TDFA achieves an output power and gain of 4.6 W and 18.8 dB, respectively, as a booster amplifier, and a gain and output power of 66.6 dB and 1.5 W, respectively, as an in-line amplifier. System-level performance evaluation using bit error rate (BER) metric for a dual-hop earth to satellite OWC wavelength division multiplexed (WDM) transmission system is also conducted.
