    Abstract: A spectroscopic assembly (7) is provided. The spectroscopic assembly includes a thermal isolation platform, a gas reference cell (40) encasing a gas (41) and attached to the thermal isolation platform, the gas reference cell (40) having at least one optically-transparent window (415), and at least one heater configured to raise a temperature of the encased gas (41). When a beamsplitter (30) is configured to reflect a portion of an input optical beam (20) emitted by a laser (10) to be incident on the at least one optically-transparent window (415) of the gas reference cell (40), the reflected portion of the input optical beam (20) is twice transmitted through the gas (41). When a detector (350) is configured to receive the optical beam (25) twice transmitted through the gas (41), a feedback signal (50) is provided to the laser (10) to stabilize the laser.

    Abstract: Optopair for use in sensors and analyzers of gases such as methane, and a fabrication method therefor is disclosed. It comprises: a) an LED, either cascaded or not, having at least one radiation emitting area, whose spectral maximum is de-tuned from the maximum absorption spectrum line of the gas absorption spectral band; and b) a Photodetector, whose responsivity spectral maximum can be either de-tuned from, or alternatively completely correspond to the maximum absorption spectrum line of the absorption spectral band of the gas. Modeling the LED emission and Photodetector responsivity spectra and minimizing the temperature sensitivity of the optopair based on the technical requirements of the optopair signal registration circuitry, once the spectral characteristics of the LED and Photodetector materials and the temperature dependencies of said spectral characteristics are determined, provides the LED de-tuned emission and Photodetector responsivity target peaks respectively.
