  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>Lithium niobate
    has emerged as a promising platform for integrated quantum optics, enabling efficient
    generation, manipulation, and detection of quantum states of light. However, integrating
    single-photon detectors requires cryogenic operating temperatures, since the best
    performing detectors are based on narrow superconducting wires. While previous
    studies have demonstrated the operation of quantum light sources and electro-optic
    modulators in LiNbO<jats:sub>3</jats:sub> at cryogenic temperatures, the thermal
    transition between room temperature and cryogenic conditions introduces additional
    effects that can significantly influence device performance. In this paper, we
    investigate the generation of pyroelectric charges and their impact on the optical
    properties of lithium niobate waveguides when changing from room temperature to
    25 K, and vice versa. We measure the generated pyroelectric charge flow and correlate
    this with fast changes in the birefringence acquired through the Sénarmont-method.
    Both electrical and optical influence of the pyroelectric effect occur predominantly
    at temperatures above 100 K.</jats:p>"
